With jdk1.6.0, javaws failed to start java application on snv b55 on some machines.

I use javaws to start a jar file, it should start java application with GUI.

OS: snv build 55,
Server: Dell Poweredge 850

1. with jdk 1.5.0_10.
2. with jdk 1.6.0, on CDE platform.
3. with jdk 1.6.0, on JDS platform under non-root user.

On above situations, the java application can be started without problem.


4. with jdk 1.6.0, JDS platform, under root user.

It always has problem, the java process seems hang there, and the GUI
will not displayed. The following is the truss info for that process:
