Paul King resolved GROOVY-7402.
-------------------------------
Resolution: Fixed
Fix Version/s: 2.4.10
Proposed PR merged. Instead of a ClassFormatError or NPE in earlier versions of
Groovy, there is now at least an error message. As we continue to look at ways
to better support combining traits and AST transformations, we can work out the
semantics would be for @Immutable or improve the error message. I'll mark as
resolved for now. Please reopen if you disagree.
