[jboss-remoting-issues] [JBoss JIRA] Updated: (JBREM-954) InterruptException should not be rethrown as CannotConnectionException

InterruptException should not be rethrown as CannotConnectionException ---------------------------------------------------------------------- Key: JBREM-954 URL: http://jira.jboss.com/jira/browse/JBREM-954 Project: JBoss Remoting Issue Type: Bug Security Level: Public(Everyone can see) Components: transport Affects Versions: 2.2.2.SP4, 2.2.2.SP7 Reporter: Galder Zamarreno Assigned To: Ron Sigal Fix For: 2.2.2.SP8 Attachments: MicroSocketClientInvokerTest.java Let's say you have a Swing GUI application that calls an EJB remotely and the client code is waiting to get entry to client side pool (controlled by clientMaxPoolSize). While waiting, the user decides to cancel the operation by interrupting the thread. In that case, the Remoting code does not make a difference between an InterruptedException and any other Exception: MicroSocketClientInvoker.java: protected SocketWrapper getConnection(Marshaller marshaller, UnMarshaller unmarshaller, int timeAllowed) throws Exception { long start = System.currentTimeMillis(); long timeToWait = (timeAllowed > 0) ? timeAllowed : 30000; boolean timedout = !semaphore.attempt(timeToWait); Any Exception thrown from getConnection() is treated as a CannotConnectException try { socketWrapper = getConnection(marshaller, unmarshaller, timeLeft); } catch (Exception e) { // if (bailOut) // return null; semaphore.release(); if (trace) log.trace(this + " released semaphore: " + semaphore.permits()); throw new CannotConnectException( "Can not get connection to server. Problem establishing " + "socket connection for " + locator, e); } The EJB3 layer wraps this in CannotConnectException in a RuntimeException like: throw new RuntimeException("cluster invocation failed, last exception was: ", lastException); This is misleading on the Remoting side. Semantically, the fact that the thread attempting to connect is interrupted shouldn't be translated into a CannotConnectException. Please find attached a test case I've created.
