Our Jenkins server suffered a power outage, and since restart, the Claim
plugin has refused to work: Clicking on the "Claim it" link for a failed
job has no visible effect.
We have uninstalled the plugin and restarted, reinstalled and restarted,
all to no avail. Nothing appears in the Jenkins log when clicking on the
Claim It link. Presumably, some sort of invalid state has been left on the
HDD of the server. The only clue I can find is the exception below.
Any suggestions?
