|Re: [p2-dev] Extending classes with generics|
PDE is just following with the rest of the Eclipse platform. To my knowledge, there is nothing in PDE requiring us to run on 1.4. So this really is a question for eclipse-dev and the PMC.
From the 'outside' (i.e. not on that PMC), it seems pretty clear to methat they haven't been acting/deciding in accord with the broader community wishes.
