Details

    Description

      Summary

      'slf4j library not found' error message in the Confluence 6 atlassian-synchrony.log

      Environment

      • Confluence 6
      • Synchrony enabled

      Steps to reproduce

      Anytime Confluence is started using Collaborative editing, the following message is printed to the logs:

      Running QueryDSL sytem...
      {"synchrony":{"message":"synchrony.querydsl.jdbc [info] connection pool test-connection-on-checkin: true idle-connection-test-period: 100 max-idle-time-excess-connections: 100 max-idle-time: 3600","ns":"synchrony.querydsl.jdbc"}}
      MLog initialization issue: slf4j found no binding or threatened to use its (dangerously silent) NOPLogger. We consider the slf4j library not found.
      MLog clients using log4j logging.
      Initializing c3p0-0.9.5.1 [built 16-June-2015 00:06:36 -0700; debug? true; trace: 10]
      

      This is printed whether Collaborative editing is working, or if its configured correctly or incorrectly.

      Notes

      Error seems to be benign as Synchrony still works, but there could be a logging issue.

      Workaround

      No workaround found so far.
