[DISCUSS] Minimum version for Groovy 6

Hi folks,

Now that 5 is out, I created a GROOVY_5_0_X branch, and master has become
Groovy 6.

We should discuss a minimum JDK version we plan to support for Groovy 6.

My current thinking is that since we are typically very conservative with
the minimum version, we should bump to JDK17. I am hoping Groovy 6 will be
delivered with a quicker window than Groovy 5, but there hasn't been any
discussion about features as yet, so it's a little hard to predict. I think
JDK17 gives us a nice increment where we can make numerous advances, and if
the release is taking longer than we expected, we can always adjust our
decision. But, I'm interested in what others think ...



Cheers, Paul.
