Even though, it would be good for backporting, I have so far excluded tests themselfs from move, as there are some additional difficulties with that. While changing test library location can be done more or less transparently, in case of tests there are some complications:
- It would be more invasive change needing changes to build system (makefiles)
- It would break existing CI testing (would require changes), in cases, where jtreg is being called directly, rater than through main makefile, (e.g. Adoptium aqa-tests, see: [openjdk.mk](https://github.com/adoptium/aqa-tests/blob/07cac1895144ecb63a2ad03c3214a52fb108cfbc/openjdk/openjdk.mk#L122) [playlist.xml](https://github.com/adoptium/aqa-tests/blob/07cac1895144ecb63a2ad03c3214a52fb108cfbc/openjdk/playlist.xml#L717).)
