The issue is that we load AOT klasses and their methods only during klass initialization - just before it calls <clinit>. It seems it is allowed to set breakpoint before that - klass needs to be loaded only. The solution is to check method()->number_of_breakpoints() before registering AOT method for it.
12-09-2018
Test class indeed is loaded before breakpoint: [0.639s][info ][class,load ] javasoft.sqe.tests.vm.jdwp.ObjectReference.InvokeMethod.invokemeth001a$TestedObjectClass source: file:/export/kvn/jck_bugs/8210220/JCK-runtime-11/classes/ === called flush_dependents_on_method() === javasoft.sqe.tests.vm.jdwp.ObjectReference.InvokeMethod.invokemeth001a$TestedObjectClass::run

We do deoptimize registerd (active) aot methods on the moment breakpoint is set. But for some reasons test class TestedObjectClass and its aot methods are loaded after that: [0.603s][trace][aot,class,load] found javasoft.sqe.tests.vm.jdwp.ObjectReference.InvokeMethod.invokemeth001a in solibs/libjcktestvm3.so for classloader 0x7febec64d840 tid=0x00007febec01d000 603 1 aot[ 1] javasoft.sqe.tests.vm.jdwp.ObjectReference.InvokeMethod.invokemeth001a.<init>()V 603 2 aot[ 1] javasoft.sqe.tests.vm.jdwp.ObjectReference.InvokeMethod.invokemeth001a.runIt([Ljava/lang/String;Ljava/io/PrintStream;)I 603 3 aot[ 1] javasoft.sqe.tests.vm.jdwp.ObjectReference.InvokeMethod.invokemeth001a.<clinit>()V 603 4 aot[ 1] javasoft.sqe.tests.vm.jdwp.ObjectReference.InvokeMethod.invokemeth001a.main([Ljava/lang/String;)V === called flush_dependents_on_method() === === found aot methods for deoptimization === 646 1 aot[ 1] javasoft.sqe.tests.vm.jdwp.ObjectReference.InvokeMethod.invokemeth001a.<init>()V made not entrant 646 2 aot[ 1] javasoft.sqe.tests.vm.jdwp.ObjectReference.InvokeMethod.invokemeth001a.runIt([Ljava/lang/String;Ljava/io/PrintStream;)I made not entrant 646 3 aot[ 1] javasoft.sqe.tests.vm.jdwp.ObjectReference.InvokeMethod.invokemeth001a.<clinit>()V made not entrant 646 4 aot[ 1] javasoft.sqe.tests.vm.jdwp.ObjectReference.InvokeMethod.invokemeth001a.main([Ljava/lang/String;)V made not entrant === exit flush_dependents_on_method() === [0.647s][trace][aot,class,load] found javasoft.sqe.tests.vm.jdwp.ObjectReference.InvokeMethod.invokemeth001a$TestedObjectClass in solibs/libjcktestvm3.so for classloader 0x7febec64d840 tid=0x00007febec01d000 647 5 aot[ 1] javasoft.sqe.tests.vm.jdwp.ObjectReference.InvokeMethod.invokemeth001a$TestedObjectClass.<init>()V 647 6 aot[ 1] javasoft.sqe.tests.vm.jdwp.ObjectReference.InvokeMethod.invokemeth001a$TestedObjectClass.pubm(I)I 647 7 aot[ 1] javasoft.sqe.tests.vm.jdwp.ObjectReference.InvokeMethod.invokemeth001a$TestedObjectClass.privm(I)I 647 8 aot[ 1] javasoft.sqe.tests.vm.jdwp.ObjectReference.InvokeMethod.invokemeth001a$TestedObjectClass.protm(I)I 647 9 aot[ 1] javasoft.sqe.tests.vm.jdwp.ObjectReference.InvokeMethod.invokemeth001a$TestedObjectClass.run()V 647 10 aot[ 1] javasoft.sqe.tests.vm.jdwp.ObjectReference.InvokeMethod.invokemeth001a$TestedObjectClass.m(I)I

For some reasons we don't deoptimize aot methods when debugger sets break point in java methods.

Looks like vm/jdwp/Method/IsObsolete/isobsolete002/ crash is covered by JDK-8210256. I will concentrate on hang in vm/jdwp/ClassType/NewInstance/newinst001 test.

Okay, thanks for verification. Vladimir, I'm assigning this to you. Please take a look or re-assign. Thanks!

Okay, thanks. Have you checked if the debuggee VM is still running (maybe there is even an hs_err file)? Maybe it crashed and that's why the debugger VM times out.
30-08-2018
Ramesh, could you please provide more information? Is the exception thrown because there is really a timeout (execution with AOT code is slower?) or is there another root cause hiding behind that exception (debuggee VM crashed)? Pre-ILW = Incorrect execution (exception thrown), with AOT compiled code, don't use AOT = HLM = P3
