Ah, thanks. Still, seems odd I'd have to just know such a thing when maintaining a 'normal' application. (But see below).

No idea. I have been struggeling with this issue ever since. I'll give out-of-the-box CDI another try and report back. Maybe it *was* just a bug in Jersey/GF and it has gone away.
Meanwhile, thanks.
