[jira] [Commented] (CONNECTORS-537) NullPointerException thrown
when displaying simple history for a connector
[ https://issues.apache.org/jira/browse/CONNECTORS-537?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13460694#comment-13460694 ]
Karl Wright commented on CONNECTORS-537:
----------------------------------------
This is the context:
{code}
String[] outputActivityList = OutputConnectionManagerFactory.getAllOutputActivities(threadContext);
String[] connectorActivityList = RepositoryConnectorFactory.getActivitiesList(threadContext,thisConnection.getClassName());
String[] globalActivityList = IRepositoryConnectionManager.activitySet;
activityList = new String[outputActivityList.length + connectorActivityList.length + globalActivityList.length];
{code}
... where the last line is line 367.
Makes no sense at all unless one of the activities lists returned is null. Probably it is the connector that is null since it has been unloaded, according to the ticket.

> 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:
