Description

The following exception gets thrown under some conditions:

Caused by: java.lang.NullPointerException
        at org.apache.manifoldcf.agents.interfaces.OutputConnectionManagerFactor
y.getAllOutputActivities(OutputConnectionManagerFactory.java:74)
        at org.apache.manifoldcf.crawler.system.ManifoldCF.getActivitiesList(Man
ifoldCF.java:1161)
        at org.apache.jsp.simplereport_jsp._jspService(simplereport_jsp.java:468
)
        at org.apache.jasper.runtime.HttpJspBase.service(HttpJspBase.java:70)
        at javax.servlet.http.HttpServlet.service(HttpServlet.java:790)
        at org.apache.jasper.servlet.JspServletWrapper.service(JspServletWrapper
.java:388)
        ... 44 more

This turns out to be related to difficulty getting a list of activities for a connector:

      String[] activities = OutputConnectorFactory.getActivitiesList(tc,connection.getClassName());
      for (String activityName : activities)
      {
        String activity = ManifoldCF.qualifyOutputActivityName(activityName,connectionName);
        map.add(activity);
      }

This probably occurs when there's a referenced but unregistered connector around.
