Impossible to restart a Confluence server

Hello,

We have the following setup:

  • Active Directory for user management,
  • JIRA version 6.4, connected to the AD,
  • Confluence build number 5983, connected to JIRA.

This setup was running fine until we had to restart Confluence. But Confluence never starts again normally, with the following stack trace:

com.atlassian.crowd.exception.OperationFailedException: Error from Crowd server propagated to here via REST API (check the Crowd server logs for details): Class type for return values ('interface com.atlassian.crowd.model.group.GroupWithAttributes') is not 'String' or 'Group'

(see the full stack trace at the end of this question).

We did not change anything in the setup (from what I know): is there a way to restart Confluence without the connection to JIRA for user management? If yes, is there a configuration file or something to edit to do so?

Thanks a lot, this is a blocking issue...!

Fred

Hi Frederic,

You are using Active Directory or JIRA for Confluence User Management ? What is your version of confluence ?

May be you have encountered this bug - https://jira.atlassian.com/browse/CONF-38736

Taha

 

 

Hi Taha, Yes we are using Active Directory, with Jira 6.4, so looks like the bug you mention is the right one... Then an upgrade to Jira 6.4.1 seems to be mandatory... Thanks a lot, Fred

Hi Taha, Everything is OK after JIRA upgrade to 6.4.11, and Confluence restart. Thanks, Fred
