Microsoft JScript compilation error

Question

For the past month until now, I'm getting the follow dialog from time to time. Probably few times a week. I'm running Windows 7 Ultimate x64 SP1 with all latest updates, and Java 6U29 (1.6.0_29-b11)

After noticing the icon on the taskbar and some trial and error, I found out that it's from jusched.exe, javaws.exe and javaw.exe. It will disappear if I end task javaw.exe.

The commandline property is

• javaws.exe:

  "C:\Program Files (x86)\Java\jre6\bin\javaws.exe"
     -silent -import -reverse -javafxau -system
     -J-Dkernel.download.dialog=false ""http://dl.javafx.com/javafx-cache.jnlp""
  

• javaw.exe:

  "C:\\Program Files (x86)\\Java\\jre6\\bin\\javaw.exe" 
    "-Xbootclasspath/a:C:\\Program Files (x86)\\Java\\jre6\\lib\\javaws.jar;C:\\Program Files (x86)\\Java\\jre6\\lib\\deploy.jar;C:\\Program Files (x86)\\Java\\jre6\\lib\\plugin.jar"
     -classpath "C:\\Program Files (x86)\\Java\\jre6\\lib\\deploy.jar" 
    "-Djava.security.policy=file:C:\\Program Files (x86)\\Java\\jre6\\lib\\security\\javaws.policy"
     -DtrustProxy=true
     -Xverify:remote
    "-Djnlpx.home=C:\\Program Files (x86)\\Java\\jre6\\bin"
     -Dsun.awt.warmup=true
     -Djnlpx.origFilenameArg=http://dl.javafx.com/javafx-cache.jnlp 
     -Djnlpx.remove=false
     -Djava.awt.headless=true
     -Dkernel.download.dialog=false
    "-Djnlpx.jvm=C:\\Program Files (x86)\\Java\\jre6\\bin\\javaw.exe" 
     -Djnlpx.vmargs=-Dkernel.download.dialog=false com.sun.javaws.Main
     -silent -import -reverse -javafxau -system http://dl.javafx.com/javafx-cache.jnlp
  

I'm wondering what is the scheduler calling, and is this a bug or just some incompatibility on my machine. I didn't find much related info from googling.

Answer 2

This error message means that there is a syntax error in your Proxy auto-config file (PAC file). Probably jusched.exe (the Java Updater) uses JScript to interpret the PAC file, because it needs to detect the correct proxy server.
