Description
JDK-8297951 got backed out with JDK-8308884 for 17.0.8 (or 11.0.20). This patch needs to be re-done for 17.0.9 (or 11.0.21) together with a fix for JDK-8307683 also targeting 17.0.9 (or 11.0.21).
Comments
Fix request [11u] I backport this for parity with 11.0.23-oracle. The redo is needed after fixing 8307683. Clean backport. Test passes. SAP nightly testing passed.
