[jdk11u-dev] RFR: 8214807: Improve handling of very old class files

Fri May 5 15:37:26 UTC 2023

I back port this for parity with Oracle JDK 11.0.20.

Backport didn't integrate cleanly. In JDK 11, the codlin option -XX:+RelaxAccessControlCheck can't be removed. It was deprecated in JDK 16.

Reviews are very welcome.

SAP-internal tests don't show any issues.
