Still debugging. What I have found: 1) no deadlocks 2) stomp library uses hawtdispatch. They then use java NIO and they open sockets and channels.
The problem is: - the thread waiting for a reply is doing the right thing: infact nothing is sent so nothing can be received. So the real problem is: the thread that must send data with nio send nothing. But if I go in debugger stepping mode it sends data! I am getting crazy, since I am 99% sure that there is no deadlock. Does the debugger disable jit? Change bytecode?
