Mail polling fails after upgrade to Confluence 4.2.1

charlesgutjahr-ourcommunity
charlesgutjahr-ourcommunity April 29, 2012

I have just upgraded our Confluence installation from version 4.1 to 4.2.1.

The mail polling feature stopped working after the upgrade, with an exception being logged every minute when the poller tries to run. That means that no new mail is picked up by Confluence. The rest of Confluence seems to be working fine, it's just the mail poller which is failing.

I have temporarily stopped the problem by disabling the 'Poll Mail' job in Administration > Scheduled Jobs. However of course we'd like to fix the problem and turn it back on.

Note that picking up the mail manually does work correctly -- ie Navigate to the workspace in Confluence, click Browse, click Mail, click 'Fetch new mail'. This will pick up the new mail just fine, without any exception being thrown. So it is only the 'Mail Poll' job which is causing the exception.

Here is a full copy of the exception that is thrown when the mail poller runs:
