That is a stack that we encounter which i find quite strange
it seems to me that WsFrameBase.processDataControl

does a wsSession.onClose(new CloseReason(Util.getCloseCode(code), reason));

when it gets an op_code close

that sounds reasonably but the problem is WsSession will call when it was
in a open state an sendCloseMessage:

if (state == State.OPEN) { state = State.OUTPUT_CLOSED;

problem is it is closed so this will result in a exception (broken pipe
stuff) when that is called

As far as i can understand it should not try to send a close message at
that point, because the close did already happen from the client side..
I guess if onclose was called programatically from the server side then it
is logical.
