Release Note: GregorianCalender.computeTime() JVM Crash - Resolved
Description
JDK-8297951 got added to the OpenJDK 11.0.19 and OpenJDK 17.0.7 releases as backports. This made a crash much more likely to occur and has been seen in the wild. See JDK-8307683 and related issues.

Until there is a more robust fix available for both JDK-8297951 and  JDK-8307683 we should back out JDK-8297951 from update releases.

Fix Request (OpenJDK 11): Please approve this back-out of JDK-8297951 (simple anti-delta). It causes regressions in Calendar::computeTime as seen in JDK-8307683 and friends. Let's back it out for 11.0.20 and try again with the redo (JDK-8309119 and backport of JDK-8307683) in 11.0.21.

FYI: I'm going to push the backout by end of my day today.

Approving for 17u. I think that reverting to the 17.0.6 status quo is the best option, given where we are with the 17.0.8 timeline (rampdown in two working days, on 2023-05-30, just one for some as Monday is a holiday in many countries). Once JDK-8307683 has soaked in trunk, it can be backported in time for the October release, if it proves stable.
