running ++2.12.0-RC1 akka-http-core/compile:doc with this additional patch (version number obtained by consulting this):

diff --git a/project/Dependencies.scala b/project/Dependencies.scala

         case _ => "0.7.0"
       }
     }

results in:

perhaps this has to do with scala/scala#5246?

@jrudolph What do you think about this issue? I tried to remove the sealed and then it works fine. We have many other sealed abstract class in the http-core model, but maybe it's only this HttpCredentials that is extended from java?

Closing here, it will be handled in akka-http. I commented in #437 (comment)
