Why do I see an error message in the Jira log when a user uses “Re-authenticate with SSO?
Jira gives an error Thread corrupted! ActionContext still references a HttpSession when the websudo is established. This does not have any functional impact.

To remove the error message from the logs, you may add this line:<logger name="com.atlassian.jira.web.filters.steps.requestcleanup.WebworkActionCleanupStep" level="OFF"/>
