Description christian.senet 2014-09-14 14:29:40 UTC 
whereas permessage-deflate is enabled, WsSession.getNegotiatedExtensions() always return an empty list.
If I use a  ServerEndpointConfig.Configurator, I see that the ServerEndpointConfig return a list with the "permessage-deflate" extension.

but in WsSession.java the current code is

    public List<Extension> getNegotiatedExtensions() {
        checkState();
        return Collections.emptyList();
    }


regards
