Most of the ci.jenkins.io builds are failing on the test: "testDispatcherTemporaryFailureRetryTest", we don't have the possibility to re-run the build even though there are some builds which failed after 4 times, which can be seen from here:

Edit:

the issue occurs now at com.microfocus.application.automation.tools.octane.tests.JUnitResultsTest (link: https://ci.jenkins.io/blue/organizations/jenkins/Plugins%2Fhpe-application-automation-tools-plugin/detail/PR-186/1/pipeline)
