[jdk11u-dev] RFR: 8300098: java/util/concurrent/ConcurrentHashMap/ConcurrentAssociateTest.java fails with internal timeout when executed with TieredCompilation1/3

Tue Jul 4 15:49:19 UTC 2023

This backport is for parity with 11.0.21-oracle. 

Patch did not apply cleanly. There was a whitespace diff which confused the merge algorithm. In addition, change [JDK-8207146](https://bugs.openjdk.org/browse/JDK-8207146) is missing: Unsafe::compareAndSetReference had to be reverted to Unsafe::compareAndSetObject 

Manual testing successful - with and without fix. 
SAP nightly tests pending.
