I fixed the Kepler/JBT 5 to Kepler/JBT 4.1.
About major version bump then I just want to point out Indigo->Juno is Eclipse 3.3 to 4.2, where as Juno->Kepler is 4.2 to 4.3 so its two different kind of jumps.
In JBT we bumped major version of JBoss tools because Eclipse bumped major versions and changed hard.
