Just small recap, why this  is done - I wanted to split full load of jcstresses, into several  HWs. At least 50, so it can finish in reasonable time. This splitting is done by groups - eg https://github.com/adoptium/aqa-tests/blob/master/system/jcstress/playlist.xml#L1128  - to have those groups equally split, information provided by this PR have to be reasonably accessible.
