Well, this is a bug with Ant. They are using an undocumented class which 
is not part of the official specification. You can't expect it to work 
with non-Sun implementations of Java. Ant needs to be fixed to include 
its own BASE64 code.

At a guess, GCJ is accidentally trying to parse classes from rt.jar, 
which do not match the ones it has already seen in libgcj.jar. 
Workaround is to remove rt.jar from your classpath.
