FYI IBM openJ9 is not supported by the Jenkins project. Initial testing has found no showstoppers, but IBM OpenJ9 introduces a very significant difference between what you're running and what is used and tested by people in the Jenkins project.
The Jenkins Platform SIG <https://jenkins.io/sigs/platform/> has started the process of evaluating OpenJ9 with the help of Jim Crowley of IBM. There are at least 4 open issues <https://issues.jenkins-ci.org/issues/?jql=text%20~%20%22OpenJ9%22%20and%20status%20%3D%20Open> related to OpenJ9 and another 15 issues <https://issues.jenkins-ci.org/issues/?jql=text%20~%20%22J9%22%20%20and%20status%20%3D%20Open> related to J9. Probably best to confirm that the same problem occurs with AdoptOpenJDK or with OpenJDK.
