Can't log in to XDoclet JIRA

On attempting to log in to the XDoclet JIRA, I get an Oops page containing the System Error & stacktrace listed below and it doesn't let me in. This occurs both from the login form on the initial dashboard page (http://opensource.atlassian.com/projects/xdoclet/secure/Dashboard.jspa) and also from the login page (http://opensource.atlassian.com/projects/xdoclet/login.jsp) that it redirects to if I click through the link to the Support Request Page.
