Since it seems that I'm the only one who experiences this odd behaviour, I
have put together a simple self-contained test case:
http://dude-development.de/enumtest.java
This example, running on Version 3.1.0-M1, always prints every value, even
those that are equal to VALUE1. If I change the comparator to equal, no
value gets printed.
Is it me who's doing something wrong or is it really a bug? Judging from
previous posts and what I read on the JIRA, Enums should work like that,
don't they?
I'd be grateful for any hints.

Best regards
Marcus
