There is no timeout reported but also no actual error, so it seems the app being debugged simply didn't run as expected.

This is another dup of JDK-8269881. "SerialNo 8" is suppose to show the stack trace of the SteadyStateThread, but it is empty: HprofReader.getStack() output: Dump file created Fri Oct 22 15:59:27 GMT 2021 SerialNo 8 SerialNo 7 java.lang.Object.wait(J)V (Object.java:(native method)) java.lang.ref.ReferenceQueue.remove(J)Ljava/lang/ref/Reference; (ReferenceQueue.java:155) jdk.internal.ref.CleanerImpl.run()V (CleanerImpl.java:140) java.lang.Thread.run()V (Thread.java:833) jdk.internal.misc.InnocuousThread.run()V (InnocuousThread.java:162) SerialNo 6 SerialNo 5 SerialNo 4 java.lang.Object.wait(J)V (Object.java:(native method)) java.lang.ref.ReferenceQueue.remove(J)Ljava/lang/ref/Reference; (ReferenceQueue.java:155) java.lang.ref.ReferenceQueue.remove()Ljava/lang/ref/Reference; (ReferenceQueue.java:176) java.lang.ref.Finalizer$FinalizerThread.run()V (Finalizer.java:175) SerialNo 3 java.lang.ref.Reference.waitForReferencePendingList()V (Reference.java:(native method)) java.lang.ref.Reference.processPendingReferences()V (Reference.java:253) java.lang.ref.Reference$ReferenceHandler.run()V (Reference.java:215) SerialNo 2 java.lang.Thread.sleep(J)V (Thread.java:(native method)) jdk.test.lib.apps.LingeredApp.main([Ljava/lang/String;)V (LingeredApp.java:599) SerialNo 1
