[vieiro]

Backport of JDK-8228960 for parity with 11.0.24-oracle This also paves the way for future container-related tests.

Tested on Fedora 40 with Docker version 27.0.1, build 7fafd33

TEST SUCCESS

Backport is clean but for a single empty newline in test/hotspot/jtreg/ProblemList.txt, that was introduced by JDK-8228904 (see commit e3aa4909 ) which was not backported to 11.
