The documentation for [this method](https://github.com/TooTallNate/Java-WebSocket/blob/cfde6e05cb5e0c525dd36030ed085d240690c564/src/main/java/org/java_websocket/WebSocketListener.java#L199) indicates it can return null in the description but then states in the Returns: never return null. Also spacing issue with "ornull" That's all, also which does it return lol.
