As noted in issue 1432, if a Python class doesn't have an implementation for an abstract or interface method, the proxy 
system generates an empty method for it.  This has always been the case, so I don't think we can change the default to 
fix it. However I'm planning on making the proxy creation class customizable in the near future, so hopefully with that a 
user could create their own proxy class creator that complains if an implementation of a Java method isn't available.
