      Description

      I upgraded a few workflow plugins that were recently released, switching from the beta version of those plugins to the released versions of the plugins. After doing that, my Pipeline jobs that were performing checkout on JNLP based Windows machines failed.

      The checkouts failed on 4 different Windows 10 machines with the same stack trace:

      The problem on all 4 machines was an outdated agent.jar file. When I use the agent.jar file that is included with Jenkins 2.138.2, it works correctly.

            It is not yet clear to me if the problem is related to a recent plugin upgrade or something else.
            I upgraded a few workflow plugins that were recently released, switching from the beta version of those plugins to the released versions of the plugins. After doing that, my Pipeline jobs that were performing checkout on Windows machines failed. The Windows agents are connected with JNLP.

            The checkouts failed on 4 different Windows 10 machines with the same stack trace:

            It is not yet clear to me if the problem is related to a recent plugin upgrade or something else.
            I upgraded a few workflow plugins that were recently released, switching from the beta version of those plugins to the released versions of the plugins. After doing that, my Pipeline jobs that were performing checkout on JNLP based Windows machines failed.

            The checkouts failed on 4 different Windows 10 machines with the same stack trace:

            The problem on all 4 machines was an outdated agent.jar file. When I use the agent.jar file that is included with Jenkins 2.138.2, it works correctly.

            Older agent.jar and slave.jar files running on the agent machine were the root cause of this problem. Once I updated the agent.jar to the version included with Jenkins 2.138.2, the jobs completed successfully.
