The pids controller is not present in 8u (JDK-8266490). This results in a test failure (NPE). Please remove it.

@jmtd This would also need fixing --^ :)

Thanks for catching. Confirmed, removed, re-tested, pushed.

The parent pull request that this pull request depends on has now been integrated and the target branch of this pull request has been updated. This means that changes from the dependent pull request can start to show up as belonging to this pull request, which may be confusing for reviewers. To remedy this situation, simply merge the latest changes from the new target branch into this pull request by running commands similar to these in the local repository for your personal fork:

git checkout 8293540-jdk8u-dev
git fetch https://git.openjdk.org/jdk8u-dev master
git merge FETCH_HEAD
# if there are conflicts, follow the instructions given by git merge
git commit -m "Merge master"
git push

openjdk · 2023-01-19T14:41:40Z

@jmtd this pull request can not be integrated into master due to one or more merge conflicts. To resolve these merge conflicts and update this pull request you can run the following commands in the local repository for your personal fork:

Done :)

@jmtd Please do not rebase or force-push to an active PR as it invalidates existing review comments. Note for future reference, the bots always squash all changes into a single commit automatically as part of the integration. See OpenJDK Developers’ Guide for more information.

Looks OK now. Thanks.
