This seems related to VT pinning support. Most likely related to other VT pinning timeouts (see #21035 (comment)). ++@fengxue-IS.

• This test employs lock.wait/notify and triggers the same assert in ContinuationHelpers.cpp that is seen in jdk24 java/lang/Thread/virtual/MonitorWaitNotify AssertionFailedError: expected: <true> but was: <false> #20369. The triggering of the assert indicates that the lock.wait use-case is not handled correctly. This failure is a duplicate of the symptoms reported in jdk24 java/lang/Thread/virtual/MonitorWaitNotify AssertionFailedError: expected: <true> but was: <false> #20369. fyi @tajila
• The test needs to be run with -Xint -Xgcpolicy:nogc -XX:+YieldPinnedVirtualThreads to enable the base VM changes for JEP 491. Also, the GC and JIT need to be disabled as the GC and VM-JIT coordination changes for JEP 491 are still in progress.
