Using Hibernate 3.2.x and either Annotations 3.2.x or 3.3.0GA I get the following exception upon configuration. I grabbed the source and discovered it's due to a method in my entity with a return type of
ArrayList<Object[]>, which commons-annotations seems to choke on. FWIW, it's not a getter of a mapped property (it's a synthetic getter.)

Is this a known issue? If not, I'll trim it down to a test case and create a bug report.

Thanks,

I don't think it's a known issue, I would appreciate a test case in a JIRA issue.

This is now ANN-668.

It seems to be specific to having a method that returns ArrayList<Object[]> rather than the almost-always-more-correct List<Object[]>. The latter doesn't trigger the exception.
