Fix deadlock with suspending the main thread while it is in Thread.join() to join the thread that is suspending it. The suspending thread then waits for a FRAME_POP event on the main thread, but that never happens because it is suspended.
Testing in progress. Running the test 100 times on all supported platforms, including separate run with `-Xcomp`. ------------- Commit messages: - Fix deadlock during join() Changes: https://git.openjdk.org/jdk/pull/21650/files Webrev: https://webrevs.openjdk.org/?repo=jdk&pr=21650&range=00 Issue: https://bugs.openjdk.org/browse/JDK-8342673 Stats: 7 lines in 1 file changed: 7 ins; 0 del; 0 mod Patch: https://git.openjdk.org/jdk/pull/21650.diff Fetch: git fetch https://git.openjdk.org/jdk.git pull/21650/head:pull/21650 PR: https://git.openjdk.org/jdk/pull/21650
