Yes. You can't have native code that depends on bytecode (except for 
weak dependencies, ie reflection)

You could compile the .jar files into shared libraries:

gcj -shared foo.jar -o libfoo.so

And then link your application against them:

gcj my/classes/*.java --main=my.classes.main -o myapp libfoo.so
