Incompatibility between python and java implementations

[GoogleCodeExporter]

What steps will reproduce the problem?
1. Create a java client/server, and a python client/server, all from one .proto 
file
2. invoke java server with java client, works.
3. invoke python server with python client, works.
4. invoke java server with python client, gets an error ( (decodeError): 
Unexpected end-group tag.)
5. invoke python server with java client, client hangs.

What is the expected output? What do you see instead?
expect successful call between platforms

What version of the product are you using? On what operating system?
tried Java protobuf-socket-rpc-2.0.jar with protobuf.socketrpc-1.3.2-py2.6.egg
tried Java protobuf-socket-rpc-2.0.jar with latest python source from svn (Sep 
28 2012)

Please provide any additional information below.

OK, if on the Java (client) side I do this, it works:

SocketRpcConnectionFactories.createUndelimitedRpcConnectionFactory
instead of createRpcConnectionFactory
