Hey guys, I've brought this topic up before without much positive response. I figure I'll bring it up again.
I'd like to propose that DeltaSpike 1.6 be the last minor release to support Java 1.6. I suspect that most users are already using Java 7 or higher. None of our builds in CI (builds.apache.org) currently run on 1.6 either, so while we can say from a syntax standpoint we're 1.6 compliant I'm not sure we can say from a JDK Library standpoint we don't rely on anything from Java 7. We're one of the few projects that probably still supports Java 6 as a mainline development, so I was hoping we could just cut 1.6 as 1.6 compliant, if we need to cut patch releases of 1.6 to apply patches, but with DeltaSpike 1.7 and on, focus on Java 7 and up.
