** END NESTED EXCEPTION **

Environment

  • Liferay DXP 7.2+

Resolution

  • This issue has been reported when using an older version of the MySQL connector (for example, 8.0.15). 
  • Use the latest version of the connector (at the time of writing, version 8.0.22) and check if the traces keep being printed.
