This is a fix of one more deadlock issue related to `interruptLock` critical sections. When the `interruptLock` is hold by the target virtual thread it is unsafe to suspend or post JVMTI events. This update is to ignore the JVMTI events when the `interruptLock` is hold. It is additionally to the cases when the target JavaThread is in a `VTMS` transition. It is based on the existing mechanism disallowing JVMTI suspends while the `interruptLock` is hold. In order to support this the target JavaThread has the `_is_disable_suspend` bit.
Testing: - Ran mach5 tiers 1-6 - There is no regression test for this issue as it is not hard to construct one. Originally, the issue was reported by JGroups which is using the `Async` profiler. ------------- Commit messages: - 8346727: JvmtiVTMSTransitionDisabler deadlock Changes: https://git.openjdk.org/jdk/pull/22997/files Webrev: https://webrevs.openjdk.org/?repo=jdk&pr=22997&range=00 Issue: https://bugs.openjdk.org/browse/JDK-8346727 Stats: 53 lines in 2 files changed: 2 ins; 0 del; 51 mod Patch: https://git.openjdk.org/jdk/pull/22997.diff Fetch: git fetch https://git.openjdk.org/jdk.git pull/22997/head:pull/22997 PR: https://git.openjdk.org/jdk/pull/22997
