Re: [m2e-dev] [m2e-users] moving m2e to java7 past kepler sr0

[Igor Fedorenko <igor@xxxxxxxxxxxxxx>]

No one can predict exact java6 usage year+ from today.

Java7 syntax makes developers more productive, so yes, it is important,
both for developers and for end users.

This is really chicken-and-egg problem, more products stay on java6,
less motivation there is for users to upgrade.

Whether this justifies move to java7, I don't know yet, but I certainly
don't plan to wait until the last user migrates off java6.
