The page http://incubator.apache.org/derby/papers/versionupgrade.html says:
Minor.major.fixpack.point or M.m.f.p
The initial version (as in the code drop from IBM) is set to 10.0.2.0
Major.minor is a typical major and minor release numbering scheme ....
I think the Major.minor should be changed to Major.minor in the first line shown above.
