That makes sense. But, in addition, we should probably make a new Jenkins job that specifically builds using “openjdk 8” b/c the current “openjdk” build uses the latest available, which is Java 11, and which is currently failing (and what prompted this whole thread). BTW, compiling with Java 10, targeting 8 seems to work, which I’ve been using for quite a while, although this is not sustainable, since Java 10 is not an LTS release. I haven’t tried 12, 13, or 14 yet.
I currently don’t see a problem (could change soon, though, pending further investigation), targeting: “compile with java 8, run with java 8+”, as well as “compile with java 11, run with java 9+”. I was just hoping that we could also add “compile with java 11, run with java 8+”, but that doesn’t look to be possible. I’m a little surprised since 11 is the next LTS release after 8, so to me, the “compile with 11, run with 8+” option seems only reasonable. But, I will work on getting the first option to happen (as in “compile with 11, run on 9+”), as you suggested.

Or make the build system understand the difference... Roger, I think it is safe for you to make a decision whether to support one or both, and if it is just going to be one, which one that is. If there are users who have opinions, give them chance to chime in and take it from there.
