Dejan Bosanac created AMQ-3955: ---------------------------------- Summary: WebSocket Transport - Race condition starting transport Key: AMQ-3955 URL: https://issues.apache.org/jira/browse/AMQ-3955 Project: ActiveMQ Issue Type: Bug Affects Versions: 5.6.0 Reporter: Dejan Bosanac Assignee: Dejan Bosanac Fix For: 5.7.0
In the StompServlet, when a websocket request comes in, we are starting up the broker's websocket connection when we call listener.onAccept(socket). Under the covers, it begins a task in a new thread to create the connection, instantiate the transport listener, and set the listener on the transport. However, this is done asynchronously, and when the StompServlet calls listener.onAccept(socket), it immediately returns to the underlying jetty websockets implementation, returning the StompSocket (which as the websocket onTextMessage listener). It seems it's possible the jetty code could call back the onTextMessage listener's onMessage(...) method and expect the StompSocket to process the Stomp message before the steps taken to complete creating the connection from the async listener.onAccept(..) call. -- This message is automatically generated by JIRA.
