Bugfix for enums

There was a bug in MoreUnit for switching in enums. This is fixed in HEAD. When writing a test for this bug I recognized that one test does not run anymore. It causes an OutOfMemory all the time. I needed to comment out this test. At the moment I don't understand why this test causes these problems becaue I just switched the eclipse version and didn't change my code. But this problem has to wait for another evening with some freetime.
