Tests for kotlinx-coroutines-debug module fail on OpenJDK 17 due to changed internals #3700
Description
When running on OpenJDK 17 (and down to OpenJDK 14 according to my checks of corresponding sources), RunningThreadStackMergeTest fails on testStackMergeWithContext, testStackMergeEscapeSuspendMethod, and testMergeThroughInvokeSuspend. The reason is a change in OpenJDK's java.util.concurrent.locks.AbstractQueuedSynchronizer$ConditionObject. This change results in a stack dump that differs from expected one by three new frames:

(nb: line numbers most probably also differ, but that's not really that relevant)
