Failed jobs: cannot assign instance of hudson.model.StreamBuildListener to field hudson.scm.SubversionSCM$CheckOutTask.listener

Recently many of my jobs fail with the following error directly after
they are started:

Building remotely on MKS Executor 1

I'm running Jenkins 1.401. Restarting the master and slave solves the
problem temporarily, but after a couple of builds the same error
occurs again.

Any ideas as to what might be causing this problem?

Can I enable any logging to pinpoint the problem? I really need to
resolve this.

Looks similar to my problem, see thread "ClassCastException during POM
parsing". I need to solve this too! So how can we help?

Kind regards,

Is it on a slave? Slaves get out of sync with masternode's libraries. Disconnect and connect them to force a new download of libraries.

Yes, the jobs that fail this way all execute on slaves.

I usually restart the Windows slave service to get the failed jobs
running again, but I don't know if that forces a new download of
libraries. At least the slave.jar files on the slaves were many months
old, so I replaced it on all slaves with a current one now. I'm not
sure if that will help anything though.
