If you are sure your jars are OK, then I think the next likely
problem is your JVM. I don't know a good way to determine all
the JVMs which may be installed, but you can tell the one
executed by doing
java -version
My Win2k machine shows
java version "1.4.2_01"
Java(TM) 2 Runtime Environment, Standard Edition (build
1.4.2_01-b06)
Java HotSpot(TM) Client VM (build 1.4.2_01-b06, mixed
mode)
Your stack trace indicates gcj is in use. I have not used that,
as I installed a Sun JDK on my Linux box, so I have no experience
with whether or not it may have the problem you are experiencing
as a bug. My only suggestion would be to install a Sun JDK and
see whether you still get the error.
