Java version history

The Java language has undergone several changes since JDK 1.0 as well as numerous additions of classes and packages to the standard library. Since J2SE 1.4, the evolution of the Java language has been governed by the Java Community Process (JCP), which uses Java Specification Requests (JSRs) to propose and specify additions and changes to the Java platform. The language is specified by the Java Language Specification (JLS); changes to the JLS are managed under JSR 901.

In addition to the language changes, other changes have been made to the Java Class Library over the years, which has grown from a few hundred classes in JDK 1.0 to over three thousand in J2SE 5. Entire new APIs, such as Swing and Java2D, have been introduced, and many of the original JDK 1.0 classes and methods have been deprecated. Some programs allow conversion of Java programs from one version of the Java platform to an older one (for example Java 5.0 backported to 1.4) (see Java backporting tools).

Regarding to Oracle Java distribution, the version 11 is a currently supported long-term support (LTS) version. ("Oracle Customers will receive Oracle Premier Support"); Oracle released for the "legacy" Java 8 LTS the last free "public update" in January 2019 for commercial use, while it will otherwise still support Java 8 with public updates for personal use up to at least December 2020.[1] Java 10 is the previously supported rapid release version. Java 10 support ended on the same date that support for Java 11 began, in September 2018. Java 7 is no longer publicly supported, and Java 9 has stopped receiving updates since Java 9 was a short-term rapid release version that has been superseded by Java 10 and now Java 11. For Java 11, long-term support will not be provided by Oracle for the public; instead, the broader OpenJDK community, as AdoptOpenJDK or others, is expected to perform the work.[2]

Java 14 General Availability occurred on March 17, 2020,[3] and a release candidate of Java 15 is now available, with Java 16 now in development.

JDK 15 is planned for release on September 15, 2020.[4] Some of the JEPs currently targeted for JDK 15 include:

History

In September 2017, Mark Reinhold, chief Architect of the Java Platform, proposed to change the release train to "one feature release every six months" rather than the current two-year schedule,[8][9] and later the proposal took effect.

JDK 1.0

The first version was released on January 23, 1996.[10][11] The first stable version, JDK 1.0.2, is called Java 1.[11]

JDK 1.1

Major additions in the release on February 19, 1997 included:[12]

J2SE 1.2

Codename Playground

The release on December 8, 1998 and subsequent releases through J2SE 5.0 were rebranded retrospectively Java 2 and the version name "J2SE" (Java 2 Platform, Standard Edition) replaced JDK to distinguish the base platform from J2EE (Java 2 Platform, Enterprise Edition) and J2ME (Java 2 Platform, Micro Edition). This was a very significant release of Java as it tripled the size of the Java platform to 1520 classes in 59 packages. Major additions included:[14]

  • strictfp keyword
  • the Swing graphical API was integrated into the core classes
  • Sun's JVM was equipped with a JIT compiler for the first time
  • Java plug-in
  • Java IDL, an IDL implementation for CORBA interoperability
  • Collections framework

J2SE 1.3

Codename Kestrel

The most notable changes in the May 8, 2000 release were:[15][16]

J2SE 1.4

Codename Merlin

The February 6, 2002 release was the first release of the Java platform developed under the Java Community Process as JSR 59. Major changes included:[17][18]

  • Language changes
    • assert keyword (specified in JSR 41)
  • Library improvements
    • Regular expressions modeled after Perl regular expressions
    • Exception chaining allows an exception to encapsulate original lower-level exception
    • Internet Protocol version 6 (IPv6) support
    • Non-blocking I/O (Java) (named NIO) (specified in JSR 51)
    • Logging API (specified in JSR 47)
    • Image I/O API for reading and writing images in formats like JPEG and PNG
    • Integrated XML parser and XSLT processor (JAXP) (specified in JSR 5 and JSR 63)
    • Integrated security and cryptography extensions (JCE, JSSE, JAAS)
    • Java Web Start included (Java Web Start was first released in March 2001 for J2SE 1.3) (specified in JSR 56)
    • Preferences API (java.util.prefs)

Public support and security updates for Java 1.4 ended in October 2008. Paid security updates for Oracle customers ended in February 2013.[19]

J2SE 5.0

Codename Tiger

The release on September 30, 2004 was originally numbered 1.5, which is still used as the internal version number. The number was changed to "better reflect the level of maturity, stability, scalability and security of the J2SE".[20] This version was developed under JSR 176.

J2SE 5.0 entered its end-of-public-updates period on April 8, 2008; updates are no longer available to the public as of November 3, 2009. Updates were available to paid Oracle customers until May 2015.[5]

Tiger added a number of significant new language features:[21][22]

  • Generics: provides compile-time (static) type safety for collections and eliminates the need for most typecasts (type conversion) (specified by JSR 14)
  • Metadata: also called annotations; allows language constructs such as classes and methods to be tagged with additional data, which can then be processed by metadata-aware utilities (specified by JSR 175)
  • Autoboxing/unboxing: automatic conversions between primitive types (such as int) and primitive wrapper classes (such as Integer) (specified by JSR 201)
  • Enumerations: the enum keyword creates a typesafe, ordered list of values (such as Day.MONDAY, Day.TUESDAY, etc.); previously this could only be achieved by non-typesafe constant integers or manually constructed classes (typesafe enum pattern) (specified by JSR 201)
  • Varargs: the last parameter of a method can now be declared using a type name followed by three dots (e.g. void drawtext(String... lines)); in the calling code any number of parameters of that type can be used and they are then placed in an array to be passed to the method, or alternatively the calling code can pass an array of that type
  • Enhanced for each loop: the for loop syntax is extended with special syntax for iterating over each member of either an array or any Iterable, such as the standard Collection classes (specified by JSR 201)
  • Improved semantics of execution for multi-threaded Java programs; the new Java memory model addresses issues of complexity, effectiveness, and performance of previous specifications[23]
  • Static imports

There were also the following improvements to the standard libraries:

Java 5 is the last release of Java to officially support Microsoft Windows 98 and Windows ME,[25] while Windows Vista was the newest version of Windows that J2SE 5 was supported on prior to Java 5 going end-of-life in October of 2009.[19]

Java 5 Update 5 (1.5.0_05) is the last release of Java to work on Windows 95 (with Internet Explorer 5.5 installed) and Windows NT 4.0.[26]

Java 5 was first available on Apple Mac OS X 10.4 (Tiger)[27] and was the default version of Java installed on Apple Mac OS X 10.5 (Leopard).

Public support and security updates for Java 1.5 ended in November 2009. Paid security updates for Oracle customers ended in April 2015.

Versioning change

This version introduced a new versioning system for the Java language, although the old versioning system continued to be used for developer libraries:

Both version numbers "1.5.0" and "5.0" are used to identify this release of the Java 2 Platform Standard Edition. Version "5.0" is the product version, while "1.5.0" is the developer version. The number "5.0" is used to better reflect the level of maturity, stability, scalability and security of the J2SE.

— Version 1.5.0 or 5.0?[28]

This correspondence continued through later releases (Java 6 = JDK 1.6, Java 7 = JDK 1.7, and so on).

Java SE 6

Codename Mustang

As of the version released on December 11, 2006, Sun replaced the name "J2SE" with Java SE and dropped the ".0" from the version number.[46] Internal numbering for developers remains 1.6.0.[47]

This version was developed under JSR 270.

During the development phase, new builds including enhancements and bug fixes were released approximately weekly. Beta versions were released in February and June 2006, leading up to a final release that occurred on December 11, 2006.

Major changes included in this version:[48][49]

  • Support for older Win9x versions dropped; unofficially, Java 6 Update 7 was the last release of Java shown to work on these versions of Windows. This is believed to be due to the major changes in Update 10.
  • Scripting Language Support (JSR 223): Generic API for tight integration with scripting languages, and built-in Mozilla JavaScript Rhino integration.
  • Dramatic performance improvements for the core platform,[50][51] and Swing.
  • Improved Web Service support through JAX-WS (JSR 224).
  • JDBC 4.0 support (JSR 221).
  • Java Compiler API (JSR 199): an API allowing a Java program to select and invoke a Java Compiler programmatically.
  • Upgrade of JAXB to version 2.0: Including integration of a StAX parser.
  • Support for pluggable annotations (JSR 269).[52]
  • Many GUI improvements, such as integration of SwingWorker in the API, table sorting and filtering, and true Swing double-buffering (eliminating the gray-area effect).
  • JVM improvements include: synchronization and compiler performance optimizations, new algorithms and upgrades to existing garbage collection algorithms, and application start-up performance.

Java 6 can be installed to Mac OS X 10.5 (Leopard) running on 64-bit (Core 2 Duo and higher) processor machines.[53] Java 6 is also supported by both 32-bit and 64-bit machines running Mac OS X 10.6 (Snow Leopard).

Java 6 reached the end of its supported life in February 2013, at which time all public updates, including security updates, were scheduled to be stopped.[54][55] Oracle released two more updates to Java 6 in March and April 2013, which patched some security vulnerabilities.[56][57]

Java 6 updates

After Java 6 release, Sun, and later Oracle, released several updates which, while not changing any public API, enhanced end-user usability or fixed bugs.[58]

Table of Java 6 updates

Java SE 6 Update 10[60]2008-10-15 HotSpot VM 11. Major changes for this update include:
  • Java Deployment Toolkit, a set of JavaScript functions to ease the deployment of applets and Java Web Start applications.[60]
  • Java Kernel, a small installer including only the most commonly used JRE classes. Other packages are downloaded when needed.
  • Enhanced updater.
  • Enhanced versioning and pack200 support: server-side support is no longer required.[60]
  • Java Quick Starter, to improve cold start-up time.
  • Improved performance of Java2D graphics primitives on Windows, using Direct3D and hardware acceleration.
  • A new Swing look and feel called Nimbus and based on synth.[61]
  • Next-Generation Java Plug-In: applets now run in a separate process and support many features of Web Start applications.[60]

The -XX:+DoEscapeAnalysis option directs the HotSpot JIT compiler to use escape analysis to determine if local objects can be allocated on the stack instead of the heap.[69]

Some developers have noticed an issue introduced in this release which causes debuggers to miss breakpoints seemingly randomly.[70] Sun has a corresponding bug, which is tracking the issue. The workaround applies to the Client and Server VMs.[71] Using the -XX:+UseParallelGC option will prevent the failure. Another workaround is to roll back to update 13, or to upgrade to update 16.

Java SE 6 Update 152009-08-04 Introduced patch-in-place functionality[72]

Java SE 7

Java 7 (codename Dolphin[136]) is a major update that was launched on July 7, 2011[137] and was made available for developers on July 28, 2011.[138] The development period was organized into thirteen milestones; on June 6, 2011, the last of the thirteen milestones was finished.[138][139] On average, 8 builds (which generally included enhancements and bug fixes) were released per milestone. The feature list at the OpenJDK 7 project lists many of the changes.

Additions in Java 7 include:[140]

  • Strings in switch[145]
  • Automatic resource management in try-statement[146]
  • Improved type inference for generic instance creation, aka the diamond operator <>[147]
  • Simplified varargs method declaration[148]
  • Binary integer literals[149]
  • Allowing underscores in numeric literals[150]
  • Catching multiple exception types and rethrowing exceptions with improved type checking[151]
  • Concurrency utilities under JSR 166[152]
  • New file I/O library (defined by JSR 203) adding support for multiple file systems, file metadata and symbolic links. The new packages are java.nio.file, java.nio.file.attribute and java.nio.file.spi[153][154]
  • Timsort is used to sort collections and arrays of objects instead of merge sort
  • Library-level support for elliptic curve cryptography algorithms
  • An XRender pipeline for Java 2D, which improves handling of features specific to modern GPUs
  • New platform APIs for the graphics features originally implemented in version 6u10 as unsupported APIs[155]
  • Enhanced library-level support for new network protocols, including SCTP and Sockets Direct Protocol
  • Upstream updates to XML and Unicode
  • Java deployment rule sets[156]

Lambda (Java's implementation of lambda functions), Jigsaw (Java's implementation of modules), and part of Coin were dropped from Java 7, and released as part of Java 8 (except for Jigsaw, which was released in Java 9).[157][158]

Java 7 was the default version to download on java.com from April 2012 until Java 8 was released.[159]

Java 7 updates

Oracle issued public updates to the Java 7 family on a quarterly basis[160] until April 2015 when the product reached the end of its public availability.[161] Further updates for JDK 7, which are scheduled to continue until Jul 2022, are only made available to customers with a support contract.[162]

Java SE 8

Java 8 was released on March 18, 2014,[223][224] and included some features that were planned for Java 7 but later deferred.[225]

Work on features was organized in terms of JDK Enhancement Proposals (JEPs).[226]

  • JSR 335, JEP 126: Language-level support for lambda expressions (officially, lambda expressions; unofficially, closures) under Project Lambda[227] and default methods (virtual extension methods)[228][229][230] which allow the addition of methods to interfaces without breaking existing implementations. There was an ongoing debate in the Java community on whether to add support for lambda expressions.[231][232] Sun later declared that lambda expressions would be included in Java and asked for community input to refine the feature.[233] Supporting lambda expressions also enables functional-style operations on streams of elements, such as MapReduce-inspired transformations on collections. Default methods allow an author of an API to add new methods to an interface without breaking the old code using it. Although it was not their primary intent,[228] default methods also allow multiple inheritance of behavior (but not state).
  • JSR 223, JEP 174: Project Nashorn, a JavaScript runtime which allows developers to embed JavaScript code within applications
  • JSR 308, JEP 104: Annotation on Java types[234]
  • Unsigned integer arithmetic[235]
  • JSR 337, JEP 120: Repeating annotations[236]
  • JSR 310, JEP 150: Date and time API[237]
  • JEP 178: Statically-linked JNI libraries[238]
  • JEP 153: Launch JavaFX applications (direct launching of JavaFX application JARs)[239]
  • JEP 122: Remove the permanent generation[240]

Java 8 is not supported on Windows XP[241] but as of JDK 8 update 25, it can still be installed and run under Windows XP.[242] Previous updates of JDK 8 could be run under XP, but had to be installed after a forced installation by directly unzipping files from the installation executable.

From October 2014, Java 8 was the default version to download (and then again the download replacing Java 9) from the official website.[243] "Oracle will continue to provide Public Updates and auto updates of Java SE 8, until at least the end of December 2020 for Personal Users, and January 2019 for Commercial Users".[1]

Java SE 9

Java SE 9 was made available on September 21, 2017,[292] due to controversial acceptance of the current implementation of Project Jigsaw by Java Executive Committee,[293] which led Oracle to fix some open issues and concerns, and to refine some critical technical questions. In the last days of June 2017, Java Community Process expressed nearly unanimous consensus on the proposed Module System scheme.[294]

  • JSR 376: Modularization of the JDK under Project Jigsaw (Java Platform Module System)[158]
  • JEP 222: JShell: The Java Shell (a Java REPL)[295]
  • JEP 295: Ahead-of-time compilation[296]
  • JEP 268: XML catalogs[297]
  • JEP 266: More concurrency updates.[298] It includes a Java implementation of Reactive Streams,[299] including a new Flow class[300] that included the interfaces previously provided by Reactive Streams[301]
  • JEP 193: Variable handles:[302] define a standard means to invoke the equivalents of various java.util.concurrent.atomic and sun.misc.Unsafe operations
  • JEP 282: jlink: The Java Linker:[303] create a tool that can assemble and optimize a set of modules and their dependencies into a custom run-time image. It effectively allows to produce a fully usable executable including the JVM to run it
  • JavaDB was removed from JDK[304]
  • JEP 263: HiDPI graphics: automatic scaling and sizing[305]
  • JEP 254: Compact Strings[306]
  • JEP 213: Milling Project Coin[307]
    • Allow @SafeVarargs on private instance methods
    • Allow effectively-final variables to be used as resources in the try-with-resources statement
    • Allow diamond with anonymous classes if the argument type of the inferred type is denotable
    • Complete the removal, begun in Java SE 8, of underscore from the set of legal identifier names
    • Support for private methods in interfaces

The first Java 9 release candidate was released on August 9, 2017.[308] The first stable release of Java 9 was on September 21, 2017.[309]

History

At JavaOne 2011, Oracle discussed features they hoped to release for Java 9 in 2016.[310] Java 9 should include better support for multi-gigabyte heaps, better native code integration, a different default garbage collector (G1, for "shorter response times")[311] and a self-tuning JVM.[312] In early 2016, the release of Java 9 was rescheduled for March 2017[313] and later again postponed four more months to July 2017.[314]

Possible future features
  • Value types, objects without identity but with an efficient memory layout.[382][383]
  • 64-bit addressable arrays to support large data sets.[384]
  • Pattern matching, a mechanism for testing and deconstruction values. This feature might be added to the switch-expression and the instance-of-expression.[385][386]
  • Sealed types, a mechanism for declaring all possible subclasses of a class. Together with the record and pattern matching features this is used to implement algebraic data types.[387]
  • Improved interoperability with native code, to enable Java source code to call functions and use data types from other languages, in a way that is easier and have better performance than today.[388]
  • Virtual threads, a lightweight user-mode scheduled alternative to standard OS managed threads. Virtual threads are mapped to OS threads in many-to-many relationship, in contrast to many-to-one relationship from original green threads implementation in early versions of Java.[389]

Implementations

The officially supported Java platform, first developed at Sun and now stewarded by Oracle, is Java SE. Releases are based on the OpenJDK project, which is a free and open source project with an open development model. Other Java implementations exist, however—in part due to Java's early history as proprietary software, while some implementations were created to offer some benefits over the standard implementation, often the result of some area of academic or corporate-sponsored research. Many GNU/Linux distributions include builds of OpenJDK through the IcedTea project started by Red Hat, which provides an easier build and integration environment.

Visual J++ and the Microsoft Java Virtual Machine were created as incompatible implementations. After the Sun v. Microsoft lawsuit, Microsoft abandoned it and began work on the .NET platform.

Other proprietary Java implementations are available, such as Azul's Zing; additionally, Azul offers certified open source OpenJDK builds under the Zulu moniker.

Prior to the release of OpenJDK, while Sun's implementation was still proprietary, the GNU Classpath project was created to provide a free and open source implementation of the Java platform. Since the release of JDK 7, when OpenJDK became the official reference implementation, the original motivation for the GNU Classpath project almost completely disappeared and its last release was in 2012.

The Apache Harmony project was started shortly before the release of OpenJDK. After Sun's initial source code release, the Harmony project continued, working to provide an implementation under a permissive license, in contrast to the copyleft license chosen for OpenJDK. Google later developed Android and released it under a permissive license. Android incorporated parts of the Harmony project, supplemented with Google's own Dalvik virtual machine and ART. Apache Harmony has since been retired, and Google has switched its use of Harmony components with equivalent ones from OpenJDK.

Both Jikes and Jikes RVM are open source research projects that were developed by IBM.

Several other implementations exist that started as proprietary software but are now open source. IBM initially developed OpenJ9 as the proprietary J9,[390] but has since relicensed the project and donated it to the Eclipse Foundation. JRockit is a proprietary implementation that was acquired by Oracle and incorporated into subsequent OpenJDK versions.

JDK 8 is not supported on Windows XP. Early versions of JDK 8 had known issues with the installer on Windows XP that prevented it from installing without manual intervention. This was resolved in JDK 8 Update 25. The important point here is that we can no longer provide complete guarantees for Java on Windows XP, since the OS is no longer being updated by Microsoft. We strongly recommend that users upgrade to a newer version of Windows that is still supported by Microsoft in order to maintain a stable and secure environment.
