That is why Context::getContextHandle() and Socket::getSocketHandle()
are declared as protected; they can only be accessed from Java classes
belonging to the org.zmq package. I believe this provides enough

Ideally they should both be private; in fact, I was sure this would STOP
things from working (since Socket needs to call getContextHandle()) but
I just tested it and it works... Surprise!

I don't know if the fact that you can call through JNI a private class
member function from member functions in another class within the same
package, is documented to always work in Java, but it SEEMS we could
declare these functions private.
