[JVM] Make 'make test' work again

[usev6]

As described in #4191
make test didn't work for a long time on the JVM backend
and gives a lot of errors at the moment.

With the changes from this PR (and one fix in NQP, that will
arrive with the next bump) make test runs fine again.
That should help to notice regressions in a timely manner.

Most of tests for Telemetry are passing now (#4354 has been resolved).

The tests for NativeCall (and some others) are still failing.

Since there is a conflict as well, I'll convert this to a draft, will take a closer look and probably force-push an updated version.

With these changes I get a successful run of "gmake test":
