I'm baffled.  I'm just running a little test program from inside 
JBuilder that invokes the JFileChooser, with a filter for only XML 
files, and I'm getting this exception thrown in the console.  Any ideas?

java.lang.NullPointerException

Which JDK are you using?
Would you post the test program?

JDK 1.4.2_06

I'll see if I can narrow down a test case.  My test program is little, 
but it's got dependencies on 2 other projects, one of which has a bunch 
of JNI stuff.
