linux-java3d problem and port?

[nikan sat]

  I installed linux-sun-jdk14 and linux java3d
1.3.1beta but sometimes it gives errors:
   ../../../bin/appletviewer GearBox.html
Jun 18, 2003 11:02:20 PM
java.util.prefs.FileSystemPreferences$3 run
WARNING: Could not create system preferences
directory. System preferences are unusable.
 
An unexpected exception has been detected in native
code outside the VM.
Unexpected Signal : 11 occurred at PC=0x35409884

Current Java thread:

javax.media.j3d.Renderer.doWork(Renderer.java:846)
        at
javax.media.j3d.J3dThread.run(J3dThread.java:250)
 
Dynamic libraries:
Can not get information for pid = 62433
 
Local Time = Wed Jun 18 23:02:26 2003

What is the problem? and i think a linux-java3d port
is necessary.
   Thank you.
