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.
