Coming soon: jtreg 7.2

[Christian Stein]

Hi JDK folk,

This is a general heads-up that jtreg 7.2 is ready for use and
that we should soon update JDK to use it. The most significant
addition to jtreg is the ability to run tests in virtual threads [1].

Find a listing of noteworthy changes at [2].

A pull request for "JDK-8304896: Update to use jtreg 7.2" [3]
will be created for review in the coming days.

Thanks to everyone who has helped thus far!

Cheers,
Christian
