Bug in akka.http.javadsl.server.directives.WebSocketDirectives?

[Qux]

Hi,

 

I want to use the WebSocketDirectives in Java.

Is it intended that  handleWebSocketMessages needs an handler of typ Flow[Message, Message, T],

but handleWebSocketMessagesForProtocol an hander of typ Flow[Message, Message, Any]?

Because of that I can not use handleWebSocketMessagesForProtocol, because of an CompilerError: 

Error:(49, 71) java: incompatible types: akka.stream.javadsl.Flow<akka.http.javadsl.model.ws.Message,akka.http.javadsl.model.ws.Message,akka.NotUsed> cannot be converted to 

                                         akka.stream.javadsl.Flow<akka.http.javadsl.model.ws.Message,akka.http.javadsl.model.ws.Message,java.lang.Object>

Thanks for your help!

This seems to be an oversight in the API, please file a ticket (and if possible a PR) about it. The materialized type should be Any (Object seen from the Java side) as it is not really passed on anywhere or consumed by anything.
