Good question. I questions that might help figure out when to drop support?
* Is Java 8 supported?
Depending on which distro of Java you're using, LTS support ranges from 2026
to 2030, so it's going be be supported for a while still. Once LTS is over, we
certainly don't need to support it, but I imagine we'll drop support before
that.
* Is there a maintenance burden to supporting Java 8?
I don't personally think so, since it's all automated with GitHub actions. I
can't recall a time where something failed on Java 8 and so we had to change
how we did something
* Are there benefits to requiring Java 11+?
I'm not familiar enough with Java 11+ to say one way or another, but being
Scala based I imagine we benefit less than Java projects might. I know back
when we supported Java 7 there were some Java 8 only classes we needed (e.g.
java.util.Base64), which in part led to dropping Java7 support, but I don't
know of any Java 11+ classes or features that we need/use.
* Do we exclude anyone by dropping Java 8?
I'm not sure on this either. I do know of systems that are stuck on RHEL7,
but I believe Java 11 is available on those systems. I suspect we don't exclude
anyone, but I'm not really sure.
I guess to me, I'd rather err on the side of caution and continue to support
Java 8, at least until it becomes a hassle to support or there's some really
nice feature that we need.
