Comments
Fix-request After backport of JDK-8163511 we are also subject to the same regression in JDK11. The original change applies cleanly after JDK-8163511. I intend to push the two together. Tier1 tests are good with this change.

This also affects JDK11 after backport of JDK-8163511.

ILW = Assert during/after class redefinition (regression by JDK-8163511), several tests at tier6, disable class unloading = HMM = P2
