In my brief try-out of it, it felt to me like if you want to do anything different (e.g. your own implementation of something), you pretty much need to switch to Scala. It's a Scala framework first and foremost.

A minor demerit was getting SBT and Play Java to work correctly in IDEA was enough of a pain to make me wonder how much overhead that was going to incur in the long run.

If someone who has used Play Java in production on a large project can weigh in on whether these points are true or not in real production use, I'd love to hear it.

We use Play Java in production, in fact it plays a central role in our backend. Our entire persistence layer is written in Java.

Going forward our new code is all in Scala. Not because we ran into issues with Play + Java, we just get fed up with Java's verbosity when dealing with futures and actors.
