Closing as a duplicate of JDK-8067946. If there are failures on other platforms, please file a separate bug. 26-08-2020 Is this still failing? This test is currently on the problem list for Windows, and I can't find any recent failures associated with this bug. I'm tempted to close this as a duplicate of JDK-8067946, or problem-list it for all platforms, since we already have coverage for this feature in the jtreg tests. 21-08-2020 And it's happening with C1 only using -XX:TieredStopAtLevel=1 suggesting that there are fundamental problems with the ReservedStackAccess annotation handling. I think the new failures are because of https://bugs.openjdk.java.net/browse/JDK-8229442 which added new uses of that annotation but those methods aren't excluded in the jtreg command line. The fact that the test requires methods to be excluded suggests the ReservedStackAccess is fundamentally broken. My recollection is that the unguarding and reguarding of the reserved stack space is done at the nmethod level instead of at the boundaries of the inlined call so if your nmethod starts executing into a reserved space then it's made available to all further execution within that nmethod until it returns. So you're basically exposed to the original problem if you call out of the nmethod after unguarding the ReservedStackAccess space. Anyway, the implementation just seems totally broken to me. 27-05-2020 So this bug was originally about running the test on Windows, and it was concluded that things don't work on Windows and so the test should not be run. The "I also see this failing on Linux" apparently arose because of JDK-8229442, and we still have an open issue in relation to that - JDK-8231031. 27-05-2020 I just checked the test with latest jdk14 and the test fails on Linux as well: java HotSpot(TM) 64-Bit Server VM warning: Potentially dangerous stack overflow in ReservedStackAccess annotated method java.util.concurrent.locks.Reentra ntLock.lock()V [1] Framework got StackOverflowError at frame = 1382 Test started execution at frame = 1126 Java HotSpot(TM) 64-Bit Server VM warning: Potentially dangerous stack overflow in ReservedStackAccess annotated method org.graalvm.compiler.hotspot.test.

We already have a JDK test that's almost identical, so I'm not sure we need to run this graalunit test in JDK at all. 19-11-2018 [~never] or [~dlong] may have some insights on this issue. 19-11-2018 Thanks for the clarifications, David! 19-11-2018 It's the StackOverflowError (in the wrong place) that can lead to a corrupt ReentrantLock. This is testing the stack reservation mechanism which tries to ensure there are no stackoverflows when executing critical lock code. With Graal involved I can easily imagine that the stack will still overflow as the Graal frames will not be accounted for in the reserved area. Update: but I didn't know about the limitation running on Windows. 19-11-2018 I wonder if this test should be executed on Windows at all. The corresponding hotspot test (runtime/ReservedStack/ReservedStackTest.java), has a special case for Windows: // Either the test passed or this platform is not supported. // On not supported platforms, we only expect the VM to // not crash during the test. This is especially important // on Windows where the detection of SOE in annotated // sections is implemented but the reserved zone mechanism // to avoid the corruption cannot be implemented yet // because of JDK-8067946 [~dnsimon], what do you think? ILW = Graal test fails (probably test bug), intermittent with single test on Windows, no workaround = MLH = P4 19-11-2018 So isn't the real failure this one? java.lang.AssertionError: FAILED: ReentrantLock 419 looks corrupted The StackOverflowError looks like it's expected and part of the normal log output of the test. Similar failures were observed with the hotspot test runtime/ReservedStack/ReservedStackTest.java and fixed in the past:
