I don't see `--generate-linkable-runtime` option is used from jmodless tests. I looked at `AbstractLinkableRuntimeTest` which provides the support to create linkable runtime image but not obvious to me. Can you describe the idea of this test framework?

OK.  I see this now (`@requires jlink.runtime.linkable` in all jmodless tests).  I.e. No test for the default JDK build.

I think this feature needs test verification even for the default JDK build.   One way to do that is to build a test image (say `base-image`) using jlink `--generate-linkable-runtime` option and then verify `base-image/bin/jlink` instead of the JDK.
