Accelerating the JDK release cadence

Exactly this.  Even if the uptake of developers applying modularity to
their own applications is a little slow, Jigsaw is still proving it's worth
many, many times over by enabling incubation modules and an enhanced
@Deprecation system.  It's truly going to allow Java to develop at a rapid
pace in a *safe* manner, the best of both worlds.

This probably hasn't been said enough, but Mark, Alan and the rest of the
Jigsaw folks - I really appreciate the work that you've done to help
accelerate Java and give it longevity.
