There are few things to note here:
1) I recently updated RunThese test  to have more testing in this areas.
2) Coleen, who helped me with class redefinition (many thanks to her!!!) pointed to the change back in 2021 related to this problem 
https://github.com/coleenp/jdk/commit/a05e8e24224b047584c3a273fa7b4fef66798dd6
However, it was not introduced the problem and we would have the same issues before the fix.
