need help debugging

Hello list,
Today I tried to get ant (1.5) build with gcj/gij from CVS (trunk). During 
the build process I got the following message:
/home/mkoch/local/java/bin/java -classpath 
build/classes:src/main::/usr/share/java/xalan2.jar:/usr/share/java/xercesImpl.jar:/usr/share/java/xml-apis.jar:

Can someone give me a tip for debugging, how to solve this issue ? Maybe its 
a bug in gcj producing wrong output or gij not knowing some input or none of 
them.
Greetings,
Michael
