The list of compatible JRE versions is out of sync again. It currently says 1.4, 1.5, and 1.6.
For trunk I believe we must remove 1.4, and we should add 1.7.
For 10.9, if we want to change it, I think we can keep 1.4? And 1.7 was out and supported before we released 10.9, right?
This issue was logged as
DERBY-5078 the previous time it was out of sync.
