That's bad. It means that you need an API that doesn't yet exist respectively is not complete. There has been a lot of work on javax.management lately, so it might work with the current GCJ trunk.
But of course that is no help right know. Try adding "-findirect-dispatch" as custom GCJ flag and hope you don't need the missing class at runtime.
Another thing that you might try is to remove the log4j jar from the compilation. I think log4j comes with GCJ/GNU classpath already.
