I have already done a preliminary review for you, and I hope to help you do a better job.

Based on the title and description of the PR, it seems that the main change is to add a JVM flag -XX:+HeapDumpOnOutOfMemoryError to the Jenkins values file to generate heap dump when the Jenkins JVM runs out of memory.

The change itself looks fine, but there are a few potential issues that should be addressed before merging.

1. Is there any reason why the Jenkins JVM is running out of memory? This should be investigated and fixed if possible. Adding the heap dump flag is a good way to diagnose the issue, but it should not be considered a permanent solution.

2. The heap dump file generated by this flag can be quite large, so it's important to ensure that there is enough disk space available to store the file.

3. The log file generated by the -Xlog flag can also consume a lot of disk space, so it's important to monitor the log files and rotate them regularly.

As for suggestions, it would be good to add some comments to the Jenkins values file explaining why this flag was added and how to use the heap dump file for debugging. Additionally, it might be helpful to add some monitoring/alerting to notify when the heap dump or log files are taking up too much disk space.
