Review comment:
Okay, that's what I was wondering - does the Java code do it
differently? And that's clearly a yes. For the record, the C++ code ignores
the possibility of 3 parts entirely, so if this message ever comes back with 3
parts geode-native apparently will get no partition information. If we were to
dig into it, we'd probably find that some version of the server in the dim past
used to send the 3-part variant, and the Java parsing code is left for
compatibility with that ancient version of the protocol.
