I'm playing with web sockets on WebSphere Liberty 16.0.0.3 and seeing something odd. If I send a number of messages back to back using the getAsyncRemote.sendText method (say 4 in a row), there are times when 2 of the messages don't make it to the client application. It feels like I'm doing something wrong, but I can't see what the issue is. Note, if I switch to the serialized approach, getBasicRemote, things work as expected and all messages are received.

Ok, did some more debugging and finally found the error. Very hidden was the following error: "java.lang.IllegalStateException: write not allowed. Most likely cause is that another Write or Close is in progress" which led to this: https://developer.ibm.com/answers/questions/253442/is-the-was-liberty-websocket-implementation-not-th.html

For now, I'm just going to switch to the getBasicRemote approach and move on.

thanks! -r
