Release build broken due to SAT using Java 17

[kaikreuzer]

Our release build is broken since May 17: https://ci.openhab.org/view/Sandbox/job/sandbox-openhab4-release/

It runs the unleash steps with Java 11 and complains that the SAT classes were compiled with Java 17 (which is true since we released SAT 0.14.0).
I'm not sure why SAT classes are loaded here at all, since we use -skipChecks=true here.

What I have figured out so far is the fact that the issue comes by loading the SAT extension (not only the plugin) in the build.

@pfink & @wborn: Would you have any good idea how we could resolve this issue?

[wborn]

Apparently you can't move extensions into a profile (see Maven Model) or disable them in some other way. So perhaps the easiest way to workaround it is to compile SAT using Java 11 again until #1475 is resolved.

Hm, I thought that SAT already uses Java 17 features as it has been updated - but it indeed still compiles nicely with Java 11. I have created openhab/static-code-analysis#451 to do this change.
We will have to release a new version 0.15.0 as we are not able to replace the version on Maven Central.
