Raw content of original issue

Junit failing randomly on some build slave nodes with:

00:02:29.418 Recording test results*00:02:29.421* ERROR: Step ‘Publish JUnit test result report’ aborted due to exception: 00:02:29.421 java.lang.NoClassDefFoundError: Could not initialize class jenkins.model.Jenkins

• environment: jenkins 2.46.3

No repository file, test, or entry point is named. Start by reproducing the failure in the JUnit report publishing step on the reported Jenkins 2.46.3 build-slave environment, then trace the NoClassDefFoundError. Done means the cause is identified and publishing succeeds reliably on affected nodes.
