NullPointerException in org.apache.maven.continuum.notification.mail.MailContinuumNotifier
------------------------------------------------------------------------------------------

                 Key: CONTINUUM-2520
                 URL: http://jira.codehaus.org/browse/CONTINUUM-2520
             Project: Continuum
          Issue Type: Bug
    Affects Versions: 1.4.0 (Beta)
            Reporter: Stephen Coy
            Priority: Critical


This appears to be a regression caused by the addition of logging:
