      Description

      A NPE was thrown when I tried to view the simple history for the file system connector. This happened after I tried to delete the connector itself and its belonging jobs.

      Apparently I managed to delete the jobs since they went away from the job list, but their status were still in the "cleaning up" state. Entries like this were shown in manifoldcf.log:

       WARN 2012-08-10 14:25:10,421 (Worker thread '4') - Pre-ingest service interruption reported for job 1335434066944 connection 'web_crawler': Http response temporary error on 'http://www.apollon.uio.no/vis/art/1998/3/intervju': 503
      

      The Agent process was running as it should.

      These problems started to occur after I upgraded from version 0.6 to 1.0 RC0.

      I executed the following prior to my upgrade:
      crawler.UnRegisterAll
      agents.UnRegisterAllOutputs
      agents.UnRegisterAll
      agents.Uninstall (slette alle tabeller i databasen)
      core.LockClean

      The configuration was exported and imported back to MCF after the upgrade.

      Environment:

      • PostgreSQL 9.1.4
      • Resin 4.0.27
      • solr-test02 mcf-1 $ uname -a

      My properties.xml looks like:
