Thanks.  This is caused because
seda.sandStorm.internal.AggTPSThreadManager$governorThread is in the
file
seda/sandStorm/internal/ATTIC/AggTPSThreadManager$governorThread.class
(In other words, it's not where gcj expects to find it.)

This is a bug in gcj.  We probably shouldn't even attempt to generate
code when a class is not in the right place in an archive, and exit
with a compiler error.  

zip -d usr/share/java/seda.jar seda/sandStorm/internal/ATTIC/\*

solves the problem.

Andrew.
