FULL PRODUCT VERSION :
java version "1.3.1_04"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.3.1_04-b02)
Java HotSpot(TM) Client VM (build 1.3.1_04-b02, mixed mode)

Java Webstart 1.0.1_02 build (b03)

FULL OPERATING SYSTEM VERSION : WIndows 2000

ADDITIONAL OPERATING SYSTEMS : build 2195 SP1



A DESCRIPTION OF THE PROBLEM :
When running our application with Java Webstart 1.01_02 we get the following exception:

Exception occurred during event dispatching:
java.lang.NullPointerException
at javax.swing.plaf.metal.MetalLookAndFeel.getControlInfo(Unknown Source)

getControlInfo is getting null when it calls getTheme (see the Swing source code, getControlInfo is
a 1 line method: getCurrentTheme ().getControInfo ()

this appears to be similar to bug# 4524547 where the wrong AppContext is being used.
 the correct AppContext needs to be used and/or
getCurrentTheme () needs to be fixed so it never returns null

we don't see the error with webstart 1.01_01 or when running as a local application
or when running with the plug-in.



STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
1. I am only able to reproduce this running our application,
but looking at the source code makes it obvious what the problem is:
getCurrentTheme() returns null
2.
3.

REPRODUCIBILITY :
This bug can be reproduced always.

---------- BEGIN SOURCE ----------
I am only able to reproduce this running our application,
but looking at the source code makes it obvious what the problem is:
getCurrentTheme() returns null.

It seems to happen very often when I have my applications debug messages enabled (a lot of output to System.out)
