> Currently, this issue is only reproducible with Dacapo sunflow.
> I tried to construct a simpler jtreg test to reproduce the issue, but can not find a way to do it till now, this task is tracked by https://bugs.openjdk.org/browse/JDK-8359045.

> So, currently I can only verify the code by reviewing it.
> Or maybe it's better to leave it until we find the test?
