Roger Whitcomb commented on PIVOT-927:
--------------------------------------
Well, I will certainly check into what got released to Maven Central ;)
So, I can make the change to our 2.0.x branch, but the bug won't be fixed until
2.0.4. Not sure how to get that to you, though, since you're using Maven....
Any thoughts?

> Can anybody give me some pointers how to workaround / fix this situation?
