DimensionType.register error?

[Criminox]

This is my code

public static final DimensionType DREAM_WORLD = DimensionType.register("DREAMWORLD", "_dream", ParallelWorldsMain.dimID, DreamWorldProvider.class, false);	

And I get this error

The method register(String, String, int, Class<? extends WorldProvider>, boolean) in the type DimensionType is not applicable for the arguments (String, String, int, Class<DreamWorldProvider>, boolean)

Im not totally sure what to do here because as far as im aware from my coding experience in this past that this was correct? 

 

Any tips?

Does your DreamWorldProvider class extend WorldProvider?
