>> @jianglizhou Thank you for filing the sub-task. You have already seen some crashes. Even though you do not have a standalone test case, it is still valuable if you describe a test scenario (at least, surfacely) which helped to observe the problem. Could you, add it to the sub-task report, please?

We probably should also consider back-porting to JDK 11 to prevent any potential changes in the area accidentally reintroducing the bug. The https://bugs.openjdk.org/browse/JDK-8312174 change has been back-ported to 11, which resolved the crashes by luck.
