I'm sorry to report that I spoke too fast. The usual random 
NullPointerException happens when - apparently - GC gets involved. It was just 
random enough to not kick in when I ran the tests in the build I first did.

PyLucene built from stock gcj 4.1.2 on Ubuntu 7.04 doesn't pass tests when 
used with Chandler. Oh well.

I'm now building the latest gcj 4.2.0 pre-release (dated 20070501)...
