> I added a new method to the ThriftTest service and I implemented the server and client in C++.  In the C++ client I added exception handling to catch TProtocolException and std::exception.  I expected that when TestClient sent in a method that the server had not implemented, a TProtocolException(NOT_IMPLEMENTED) would be returned.  The server log indicates it got to this point in theory:
> {noformat}
> ERROR:root:'TestHandler' object has no attribute 'testRequired'
> Traceback (most recent call last):
>   File "/home/jking/thrift/github/thrift/test/py/gen-py/ThriftTest/ThriftTest.py", line 1593, in process_testRequired
>     self._handler.testRequired(args.req)
> {noformat}
> However on the C++ client side, a std::exception was received and NOT a TProtocolException, which is a bug:
> {noformat}
> testClient.testRequired() =>*** FAILED *** got back std::exception Internal error
> {noformat}
