We have Multijobs with parameters that is passed down to the slaves and written to file for consumption. After an automatic upgrade to LTS 1.651.2 the only content in parameters.properties are a time-stamp and effectively failing all jobs as no parameters were found.

There was an update for the multijob plugin after the upgrade, but that did not fix the problem.
I could not see anything useful in the logs.

After reverting to LTS 1.651.1 it works again.
