Java includes the bytecode standard, so JARs are compile-once,
run-anywhere. I beleive the major problem I ran into when trying to
run JOSM on GCJ is that the classpath libraries are not up-to JDK 1.5
yet. When I try with GIJ I get:

Caused by: java.lang.ClassNotFoundException:
java.util.concurrent.Executor not found in

I havn't yet worked out how to get GIJ to use the sun libraries. But
in any case, to get it to work you either have to find a way of
getting JOSM not to use that class, or convince someone to add support
for it to Classpath.

(Note: I'm not claiming this is the only class it's missing, this is
just the first ti complains about).

Have a nice day,
