[Bug swing/24077] New: Cannot create JFileChooser due to NPE (getFontMetrics)

[hendrich at informatik dot uni-hamburg dot de]

Swing is almost completely broken at the moment (due to changes introduced
by the recent repaint refactoring). There are NPEs all over the place.
Here is my favorite, stacktrace from jamvm 1.3.2 and Classpath CVS 2005.09.29 
on x86 linux:
