Java application crashes on startup in citrix session

Question

We have a java application published through citrix. When application is launched for a new user, it crashes immediately on startup.

If we login using RDP, then log out (not starting the app), it starts to work.

We've published another smaller java app, and it works for new users, without the need to first log on using RDP.

Steps:

- Publish java app
- create new user
- run published app in citrix -> crash
- log on user using rdp, log out
- run published app in citrix -> works fine

Its becoming real tiresom to log on each new user to each citrix server :-P

The problem was related to the specific code, which read AppData setting from registry.

This is from netbeans launcher (which is possibly changed in later versions)

char* getUserHomeFromRegistry(char* userhome)
{
    HKEY key;

    if (RegOpenKeyEx(
            HKEY_CURRENT_USER,
            "Software\\Microsoft\\Windows\\CurrentVersion\\Explorer\\Shell Folders",
            0,
            KEY_READ,
            &key) != 0)
        return NULL;

    char *path = GetStringValue(key, "AppData");
    RegCloseKey(key);

    strcpy(userhome, path);
    return userhome;
 }

This registry setting is not always available, which then causes a crash.

However, %APPDATA% env variable is, so we made logon app that sets registry if it is not available.

Thanks Mr Zanchenko for finding the cause and solving it!
