we are trying to get a little project running on an embedded system. The java environment is cacao + gnu classpath. We want to get a simple rmi example running.
We can successfully bind the server instance without any problems at all. But when launching the client (which just does a lookup and a call of one remote helloworld-function) it crashes.

error in client
Any ideas on this one? We don't have a clue what the error could be.
We already checked that the java code is compiled with java 1.5. Maybe it's something with the stub-generation of classpath?
