FULL PRODUCT VERSION :
Java(TM) 2 Runtime Environment, Standard Edition (build 1.3.1_03-b03)
Java HotSpot(TM) Client VM (build 1.3.1_03-b03, mixed mode)

FULL OPERATING SYSTEM VERSION : Windows 2000


A DESCRIPTION OF THE PROBLEM :
The Java Web Start Application Manager throws an exception
when I click the Advanced tab (in File->Preferences).

I've recently discovered that the problem doesn't occur when Web Start is
initially installed. I am actually able to set the log options through the
Java -> Preferences -> Advanced tab within the application manager. That
is, until I download my application. This is true for both 1.0.1 and 1.2.

The problem does occur with Web Start 1.2 with a slightly different twist.
i.e. the application manager crashes when I click the Java -> Preferences
-> Advanced tab. Below is the stack trace that is written to the log file.

Bug 4634008 reported seeing the same exception as well as a problem with
the registry, but I'm not seeing the StringIndexOutOfBoundsException that
was also reported in that bug.

STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
1. Start the Java Web Start Application Manager
2. Click File->Preferences
3. Click Advanced

EXPECTED VERSUS ACTUAL BEHAVIOR :
The "Advanced" tab should be displayed. Instead, nothing
happens.
