        Tests:
        java/util/stream/test/org/openjdk/tests/java/util/stream/SequentialOpTest.java
        Product tested on: mach5-one-jdk-17-0-6+2-152-tier5 (CI build)
        OS/architecture: Windows-x64-debug, linux-x64-debug builds
        Reproducible: Intermittent, once in 100 times
        Is it a Regression: No, it's an intermittent crash. I have seen it only once in the CI run.
        Is it a platform-specific issue: currently seen with Windows-x64-debug, linux-x64-debug builds.
