Erlend Garåsen created CONNECTORS-537:
-----------------------------------------
Summary: NullPointerException thrown when displaying simple
history for a connector
Key: CONNECTORS-537
URL: https://issues.apache.org/jira/browse/CONNECTORS-537
Project: ManifoldCF
Issue Type: Bug
Components: Framework core
Affects Versions: ManifoldCF 1.0
Reporter: Erlend Garåsen
Fix For: ManifoldCF 1.0
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
{code}
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
Linux solr-test02.uio.no 2.6.18-308.4.1.el5 #1 SMP Wed Mar 28 01:54:56 EDT 2012
x86_64 GNU/Linux
