I believe I've found the issue. It's the Integer.MIN_VALUE priorities on those two classes.

Haha, nice, you got me there. I certainly didn't expect that
I think I never saw a negative priority usage within CDI in the first place, but the spec doesn't seem to forbid it so this is a bug we need to fix.

Karl von Randow would you be interested in submitting a PR containing a fix + test or should I do it?
