play-authenticate-usage-scala | Scala version of the usage sample | Learning library

What I'm asking is how to get hold of the Default Scala Play BodyParser implementation in 2.6. However, if you know a cleaner way to solve this use-case I'm more than happy to hear it.

Some preamble ... I reused a Java Play framework Play-Authenticate (PA) to build a Scala Play application on top. Yes crucify me for it! I wanted all the social authentication functionality but have my application in Scala and use e.g. Slick. Yes yes I could try rewriting PA in Scala but no time now ... thinking about it though.

Now that this is out of the way, here is my use case. I have Scala controllers and need to pass Java Context to the PA framework to be able to use it. I also need to check whether the user can be cookie-authenticated, namely whether the user checked the "Remember Me" box when she logged the first time. This "solution" used to work before migrating to Play 2.6 but now doesn't work because of the BodyParser.

This is what the "burger" looks like. I want to eat it so ... I need to authenticate the user by checking the incoming cookie but while at it a Java Context is created (to interoperate with PA). But since I have the dreaded Java Context I can make it available throughout the Scala Application in the scope of one request:
