--- Comment #1 from Konstantin Kolinko <kn...@gmail.com> ---
What are you trying to do here and what do you expect? Is it a real use case? 

(Source code =?)

My expectations are that such call is expected to fail.

For reference, WsSession.addMessageHandler(WsSession.java:198) method called
here is

[[[
    @Override
    public void addMessageHandler(MessageHandler listener) {
]]]

declared in javax.websocket.Session.

Use of that method is discouraged in favor of WebSocket 1.1 methods

Session.addMessageHandler(Class<T> clazz, MessageHandler.Partial<T> handler)
Session.addMessageHandler(Class<T> clazz, MessageHandler.Whole<T> handler)
