After upgrading from 1.377 to 1.382, jobs which were configured to use the jDepend plugin have their historical jobs all marked as FAILED. Any new job which runs will be marked as SUCCESS, but inspection of the build.xml shows no <result/> element. Reloading Hudson's configuration from disk results in this latest job to be changed to FAILED.

The workaround is to disable the jDepend plugin from all jobs, but the history of previous jobs is not recoverable without backups.

After the job runs, the stack trace below is observed in the log.
