JDK-8064811 replaced uses of CHECK_NULL with THREAD in return statements. It has been backported, but there are still places in 8u where CHECK_NULL is used in a return statement. They should be fixed.
JDK-8062808 has been backported, see JDK-8254172.
Removing jdk8u-fix-request as the idea, I think, is to get JDK-8062808 backported instead.
When I worked on this clean-up, I realized that the upstream had fixed it. That's why I said it's subset of JDK-8062808.
I suggest we close this one and just work on the backport of JDK-8062808. I will resend the code review.
I don't see a reference to the review thread. Please add it and we'll consider it.
It's a subset of JDK-8062808.
I have requested to backport it to jdk8u. I will close this one if it is approved.
