Eric Milles commented on GROOVY-7934:
-------------------------------------
I missed the ClosureParams metadata because it is not showing in the javadoc.
(I’ll look into that.) It says the closure takes U and E as params. I think U
should be V or T.
This does not account for the cast exception. I’m checking on that still.
