I am trying to query an external database using the Database Connector.  In my userlib I have replicated, unpacked and looked at the class (SQLServerDriver.class) myself in powershell and found that it was compiled with java 11 (class version 55). When removing that jar, the database connector still runs and with the same error. Trying to add a different jar doesn’t seem to work as it still uses whatever was compiled by java 17. How can I find exactly what jar is being used so I can atleast remove it? Pictures of what I believe to be the relevant files (the bottom is the one that was unpacked and checked in powershell) Action Manager Stack Trace, is there something I’m missing? : Error in execution of monitored action 'RegularClientAction' (execution id: 1653336975562-6, execution type: CLIENT) -------- java.lang.UnsupportedClassVersionError: com/microsoft/sqlserver/jdbc/SQLServerDriver has been
