The common way to "skip" the test that are incompatible with some JDKs is to record them as "soft errors", which make them skipped. This is what [CODETOOLS-7903695](https://bugs.openjdk.org/browse/CODETOOLS-7903695) did, and it is supposed to be enough.

Ok. you are right. They are just api-mishmash, so soft errors, so  ignored. Not sure when I run it last so it was so intrusive it led me to  create and elaborate on CODETOOLS-7903671. That sounds like this PR is indeed no go. 

I'm tempted to add the `alignment(1)`  variants so jdk24+ do not suffer the lack of coverage. What is your advice here?
