Create Oracle Connection: Cannot load connection class because of underlying exception: com.mysql.cj.exceptions.WrongArgumentException: Malformed database URL, failed to parse the main URL sections.

On save of the connection a strange MySQL related error is shown although I am creating an Oracle connection. This worked fine in the previous version of db connect.

Version 3.1.4, must be related to pi

I had the same problem in Splunk 7.3.4.2 and DB-Connect 3.2.0
I tried to made a new Oracle-DB-Connection and got mySQL error message. When I removed mySQL driver from DB-Connect I got the correct error message from Oracle jdbc driver.
As suggested by earlhelms it seems to be a bug in the mySQL jdbc driver, so I updated this driver from version 8.0.11 to 8.0.19 and this seems to solve the issue.

Bug #87600 Connector throws 'Malformed database URL' on non mysql connection-urls

Incidentally, only one of may many Oracle databases is having this issue and it only started following an Oracle upgrade.

I'm having the same issue and it only started after an Oracle database upgrade. An existing working database input started displaying this message and stopped working.
