Accepting java parameters on controllers without conversion to java.lang.String.

By checking the parent of each instance variable class on the controller, we can
be sure if it's a Rjb::Rjb_JavaClass or Rjb::Rjb_JavaProxy instance.
Example cases like Rjb::Java_lang_String or Rjb::Java_util_HashMap will also be
as they are.
I'm not sure if we can receive a Rjb::Rjb_JavaBridge, but it will work too.
