Nullpointer when creating JFileChooser

Question

I am launching a regular java app in a Desktop I created ( CreateDesktop() ) on a Windows 7 64 bit box. The code is all compiled in 32 bit, and the JVM being used to launch the app is also 32 bit. IN this application I create a JFileChooser object, JFileChooser fc = new JFileChooser(); etc, etc, etc.
This and all the other code associated with it works fine. When I take all the same identical binaries, JVM and all, to a Windows 7 32 bit box JFileChooser throws a null pointer exception when creating it.
The app also work just fine in the 32 bit machine if I launch it in the default Windows destop.
Does anyone have any idea what's going on and the inconsistency between Windows 7 32 bit and 64 bit?
Thanks Al Harper

Answer 1

For the person that asked here's the code snippet:
JFileChooser chooser = new JFileChooser();
File f = new File("resources");
It never makes it to the File f = new File("resources") line.
This is very old code that has been running for 10+ years on a variety of Windows OS's. This problem didn't start till Windows 7.
For gimbal2 ... Your statement "You apparently don't even consider that your own code can have a problem" is a rude and arrogant statement. We always consider that possibility. We are NOT JVM pessimists. I come to these post for help, NOT JUDGEMENTS!!! Keep your opinions to yourself!
