Improve Weak CAS VarHandle/Unsafe tests resilience under spurious failures

    XMLWordPrintable

Details

    Backports

      Description

        We have a few reports that existing Weak* VarHandle tests are still flaky, for example on large AArch64 machines or small RISC-V machines.

        The flakiness is intrinsic to the nature of Weak* operations under tests, that can spuriously fail. The last attempt to fix these was JDK-8155739. We need to strengthen these a bit more.
