Ok, I see what happened. The test always failed and is part of test/jdk/ProblemList-graal.txt. However the tests was recently moved from java/lang/Runtime/exec/ to java/lang/RuntimeTests/exec/ but corresponding entry in ProblemList-graal.txt was not updated.

While I am agree that the test can easy fail with Graal as it is not aware of objects allocation triggered by Graal I don't understand why this failure started to appear recently. I launched mach5 testing of this test on macos with 3 jdk14 builds - b15, b26, b27 and the test failed almost every time. So the failure is not related to recent jdk/hs changes. Could it be we did some changes in macos hosts configurations which started to provoke this error more frequently? Leonid [~lmesnik]?

ILW = MMM = P3 (For now triaging this one as P3 testbug for 14.) Hi [~epavlova], please review this task. Also can this be closed as duplicate of JDK-8196611? Thanks
