I simplified a bit and now explicitly wait for all responders to JOIN but I'm getting the same results. I can't see any real difference between your test and mine. I think my test is correct unless I'm doing something really dumb that I can't see.
Incidentally, if I lower the pause to 0, the ZreInterface.send() starts blocking, which I think is the behavior we'd expect. We prefer to use the pure java version of Zyre so that we can use it in Android. We'll use the C library for other platforms.

What I'd do is simplify it, and see when it starts happening. If you are able to write a JNI layer then we could eventually wrap the Zyre C API in Java.
