>> Backporting JDK-8365065: Cancelled ForkJoinPool tasks no longer throw CancellationException. Fixes the exception propagation and tests. Based on the original bug it is a regression and it last worked in version 17.0.16. Ran GHA Sanity Checks (passed), jtreg tier1 tests (passed) and related tests (passed) on linux-x64, linux-aarch64, macos-aarch64 and windows-x64:

@GoeLin I edited the existing approval comments on the other PRs pending approval.

Before I proceed with this current PR. It is modifying the exception propagation back to be compliant with the specification, but it does make a modification in the javadoc. Is expectation to remove the javadoc comment changes from the backport so it just entails behavioral changes?
