[Twisted-Python] Referenceable interfaces in Java

Any suggestions on how to deal with keywords args in Java PB referenceables? If I just ignore them I can make methods in Referenceables be a lot more normal looking: public Object remote_foo(Integer x) instead of: public Object remote_foo(Object[] args, Map kwargs) And allow method overloading too. I could of course implement both policies in different classes, in which case I'd be happy for suggestions on a name for such classes.
