Hi Team
I'm facing an issue with Oracle JDeveloper 12c where the Database Navigator is not functioning as expected.
Steps to Reproduce:
- Launch JDeveloper 12c
- Navigate to Window → Database
- The Database Navigator window does not open & showing below screenshot error.
Could anyone guide me on how to troubleshoot or restore the Database Navigator functionality?
Is there a specific configuration, plugin, or workaround that needs to be done for this to work?
