Infer Nullity on Interface (implementation already annotated)

Hi,

I am currently introducing the nullity annotations, stating on the database layer. First, I used Analyze -> Infer Nullity on the implementation, then completed the annotations manually. Now, every method and every parameter in the implementation is annotated.

When I open the interface and run Analyze -> Infer Nullity on the current file, I only get the return types inferred. Parameters are not, although there is only one implementation of the interface.

Is there some method other than copy/paste all method declarations from the implementation to the interface ?

I am unsing IDEA 11.1.5 Ultimate

Thanks and Regards,
Markus
