Only running the @AllEmfTests@ results in this NPE:

Comment 2 Miles Parker

Fixed the second one but I can't repreduce the first.

Comment 3 Benjamin Muskalla

2011-08-29 18:47:08 EDT

I think I was just running all tests in the project and didn't use the suite.

Comment 4 Miles Parker

2011-08-31 13:11:42 EDT

OK, I can't reproduce that -- all tests pass on my end. Please retry and reopen if you're still seeing it.
