CloseReason always null for WebSocket onClose methods ----------------------------------------------------- Key: WFLY-3109 URL: https://issues.jboss.org/browse/WFLY-3109 Project: WildFly Issue Type: Bug Security Level: Public(Everyone can see) Affects Versions: 8.0.0.Final Environment: WildFly 8.0.0.Final on Windows 7 Pro (64 bits) with JDK 7.0u51 (64 bits) Reporter: Tom Tom The onClose method of the websocket endpoints does not receive valid CloseReason, it is always null. With GlassFish 4.0, the CloseReason is not null and correctly reflects the code and message used to close the wensocket from the client side. Simplified code sample of the endpoint: @ServerEndpoint(value = "/test", configurator = MyConfigurator.class) public class MyEndpoint { // onOpen, onMessage and onError, LOGGER are omitted @OnClose public void onClose(Session session, CloseReason reason) { LOGGER.debug("onClose(sessionId={}, reason={})", session.getId(), reason); } }
