Hello Mandy, this change to use the underlying cause of `ResolutionExcepion` and `FindException` when reporting the error message, appears OK to me.

I didn't know if `ResolutionException` too wraps the actual cause underneath, so I looked around a few JBS issues where `ResolutionException` was reported as being thrown and it does appear that the actual cause lies underneath. So I think this change is fine.
