        Here's the crashing thread's stack:

        This looks like the same failure mode as:

        JDK-8257999 Parallel GC crash in gc/parallel/TestDynShrinkHeap.java: new region is not in covered_region

        which was fixed in jdk-16-B30 (build ID: jdk-16+30-2130)
        and this failure occurred in jdk-16+31-2146-tier1.
