Build Failed
https://jenkins.ovirt.org/job/standard-enqueue/32675/ :
This change was not submitted to any change queues for system testing. You will need to create some 'build-artifacts' jobs if you want changes to be submitted to change queues, take part in the system tests and be deployed to the nightly snapshot repositories. If your project uses STDCI V2 and you have release branches configured, you may disregard this message.

AFAIU, this ^^^ ran:

Which failed with:

Quickly looking at the code, it seems like we keep somewhere in
"exported-artifacts" cached picked objects, and above fails when
trying to load them.

I guess it might include too-old code and should be refreshed
(hopefully, if we did this the way I expect we did, by just finding
the file ("<class name>.dat") and removing it).

Last successful run of this job was a month ago.

Anyone is taking care of this?

Thanks,
