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.
