> I have stumbled upon this bug partly by accident, and I'm not convinced it's a valid
use case, but either way it should not crash the compiler with a NPE.
> Trying to compile the following simple class:
> {code}
> import groovy.lang.Delegate
> class BugsMe {
> 	@Delegate
> 	byte[] file
> }
> {code}
> Results in the following exception:
> {code}
> >>> a serious error occurred: BUG! exception in phase 'canonicalization' in
source unit 'BugsMe.groovy' unexpected NullpointerException
> >>> stacktrace:
> BUG! exception in phase 'canonicalization' in source unit 'BugsMe.groovy' unexpected
NullpointerException
