+Subject: [PATCH] Fix premature player kicks on shutdown
+
+When the server is stopping, the default execution handler method will throw a
+RejectedExecutionException in order to prevent further execution, this causes
+us to lose the actual kick reason. To mitigate this, we'll use a seperate marked
+class in order to gracefully ignore these.
