      Description

      The trigger mechanism does not seem to work for FTP URLs. I get the following information shown in the URLTrigger log:
      [URLTrigger] - Poll with a URL
      Polling started on Apr 4, 2013 9:44:47 AM
      Polling for the job testjob
      Looking nodes where the poll can be run.
      Looking for a node to the restricted label master.
      Polling on master.
      Failed to poll URL: java.lang.NullPointerException
      Skipping URLTrigger initialization. Waiting next schedule
      Polling complete. Took 8 ms.
      No changes.

      I also find the following log messages in the jenkins logs:

      SEVERE: Severe error on trigger startup null

          The error message has disappeared but FTP URLs still do not function correctly. Have a look at the attached FTPtestJob.tar.gz job configuration. I expect a build to be triggered at least once, but the URL trigger log always indicates "no change".

          Added example job showing malfunction. The job should be triggered to build at least once.

          FTP polling is working when we give 'anonymous' in user field under 'URL Poll trigger/Advanced/Basic Authentication' if anonymous user exists.

          Now works with fix applied and explicit setting of user to anonymous.
