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](https://bugs.openjdk.org/browse/JDK-8155739). We need to strengthen these a bit more. The actual values depend on the successful testing on known-failing platforms. I ballparked bumping the attempts 5x and introducing the delay would help without exploding test time in worst cases. ------------- Commit messages: - Fix Changes: https://git.openjdk.org/jdk/pull/9889/files Webrev: https://webrevs.openjdk.org/?repo=jdk&pr=9889&range=00 Issue: https://bugs.openjdk.org/browse/JDK-8292407 Stats: 297 lines in 26 files changed: 296 ins; 0 del; 1 mod Patch: https://git.openjdk.org/jdk/pull/9889.diff Fetch: git fetch https://git.openjdk.org/jdk pull/9889/head:pull/9889 PR: https://git.openjdk.org/jdk/pull/9889
