code works in 1.8 in prod and dev enviroment and in 11 only in dev enviroment

[MoeQuadrat]

hello,
I have this code. I use it in the play framework in scala, the code works fine in dev mode. But when I use production mode it does not find the classes it found in dev mode. I then decided to downgrade my Java from 11.0.14 to 1.8 and suddenly the code works in both modes. But unfortunately I can't use My Projects in 1.8 because I need compatibility with Java 11 for some other dependencies.

val x = reflection .getSubTypesOf(classOf[AutoRoutableController]) .asScala println(x)
