SubProtocolWebSocketHandler - No handlers

问题

I have this ugly error during deploying Spring app on JBoss.

This error occurred during init SubProtocolWebSocketHandler. I also paste below my MessageBroker implementation.

@Configuration
@EnableWebSocketMessageBroker
@Component("messageBroker")
public class MessageBroker implements WebSocketMessageBrokerConfigurer {

    @Override
    public void registerStompEndpoints(StompEndpointRegistry stompEndpointRegistry) {
        stompEndpointRegistry.addEndpoint("/random").withSockJS();
    }

    @Override
    public void configureMessageBroker(MessageBrokerRegistry messageBrokerRegistry) {
        messageBrokerRegistry.setApplicationDestinationPrefixes("/app").enableSimpleBroker("/queue", "/topic");
    }

    @Override
    public void configureWebSocketTransport(WebSocketTransportRegistration webSocketTransportRegistration) {
    }

    @Override
    public void configureClientInboundChannel(ChannelRegistration channelRegistration) {
    }

    @Override
    public void configureClientOutboundChannel(ChannelRegistration channelRegistration) {
    }

    @Override
    public void addArgumentResolvers(List<HandlerMethodArgumentResolver> handlerMethodArgumentResolvers) {

    }

    @Override
    public void addReturnValueHandlers(List<HandlerMethodReturnValueHandler> handlerMethodReturnValueHandlers) {

    }

    @Override
    public boolean configureMessageConverters(List<MessageConverter> messageConverters) {
        messageConverters.add(new MappingJackson2MessageConverter());
        return true;
    }
}

I must to add that I am using Spring 4.1.3.RELEASE and Spring Messaging 4.1.3.RELEASE. Thanks for help!
