Crash in AbstractComponent after reconnection

Tinder
1

Tinder’s AbstractComponent class crashes if it receives a packet after having being reconnected to the server.

Indeed, the executor is shutdown but reused in processPacket (RejectedExecutionException).

A correction is to test if the executor is shutdown in the start command (current code just tests the null pointer).

if (executor == null || executor.isShutdown()) {                executor = new ThreadPoolExecutor(maxThreadPoolSize,                          maxThreadPoolSize, 60L, TimeUnit.SECONDS,                          new LinkedBlockingQueue<Runnable>(maxQueueSize));           }

Patch attached.

Thank you for your bugreport. You’re quite right, the component should be restartable. I’ve created a JIRA issue for this: TINDER-31.
