If I'm not mistaken, there are currently no concurrency guarantees in the spec for Socket and SSLSocket.
Specifically, I'm interested whether two different threads can use the the streams returned by getInputStream() and getOutputStream() without synchronization. (This is useful for implementing full-duplex connections without having to wrestle with SSLEngine.) Peeking at the implementation of SSLSocket, I see that there is quite a bit of locking performed in there. Is this expected to be sufficient for the scenario I outlined?
