[jira] [Resolved] (GROOVY-4811) exception while compiling annotation type

["Paul King (JIRA)" <ji...@apache.org>]

Paul King resolved GROOVY-4811.
-------------------------------
       Resolution: Fixed
    Fix Version/s: 2.5.0-beta-1
         Assignee: Paul King

This can be considered a bug (unneeded difference from Java) or new feature (a convenience syntax we didn't use to support but will now). Certainly IDEA also complains about the syntax - so there is 3rd party tool implications for this change. For that reason I'll do the change just in 2.5 for now.

If there is a huge demand, we could consider back-porting to the 2_4_X branch.
