Move examples to Java 11? about osgi-test HOT 8 CLOSED

failing to build in CI with Java 8 because Gradle uses a version of Logback that requires Java 11

Gradle does not use this. It is used by the example. I reverted #760 and we will need to tell dependabot to only use logback 1.3.x for the examples.

Since it is just examples.. is would go 21

We had previously been using a build matrix to prove that we remained compatible with all of the target java versions for osgi-test, which still has a base of Java 8. I would have expected that we might drop 8 from the matrix but keep 11, 17 and 21.

and maybe LASTEST

You can build with Java 17 (or 21) and still target Java 8. So I don't see any real reason to move the examples from their current state.

I am not sure why you would drop Java 8 support. Bnd did because we wanted to exploit changes in the language in the large code base that is Bnd and Bnd is mostly a tool and not a runtime. I don't think osgi-test would really benefit like that and it would break downstream users who still require Java 8 as their runtime (and there are still many of those).

The gradle example builds are currently failing to build in CI with Java 8 because Gradle uses a version of Logback that requires Java 11. I'm not proposing to drop Java 8 for osgi-test, but at the moment all PRs have a failing check.

Looking at the failed build, the issue is with a Logback update to 1.4 which no longer supports Java 8. Perhaps the answer is to revert #760 and then tell dependabot to ignore logback 1.4 when it next proposes to update to 1.4.
