When Transparent Huge Pages (THP) are enabled JVM will either crash or gets stuck in a tight loop when it encounters a nullified page in its heap. The corruption starts at a 1MB heap segment boundary and usually means 1 page at the segment start is nullified. The problem disappears when THP is disabled.
