This is an inconsistancy in the class file format. You probably compiled
java-gnome with jikes. (the makefiles automatically pick a java compiler to use,
preferring open source ones). As default, this generates class files which are
too new for sun/blackdown java. This can be overridden with jikes --target 1.3.
To make java-gnome do this, you would have to modify the makefiles.

Alternatively, use another compiler for the job:
export JAVAC=javac before running autogen and make will make the scripts use
javac rather than jikes.
If you do this, be sure to remove all jar and class files first (make clean
should do this for you), otherwise some may not be recompiled.
