Well, for the time being you can just change the Format class code itself.

Is it a bug? I'd call it an RFE more than a bug. It's behaving as
expected, we just never anticipated your use case. I don't see a
problem with enhancing JDOM to differentiate between null and empty.
Why don't you try changing Format internally, do a build, and let us
know if it fixes your problem. Then send in the change as a patch file.
