Thanks for reporting. It appears the MariaDB JDBC driver optionally requires JNA (which Flyway doesn't ship with) and this must be a case where it is used.

Can you try downloading https://search.maven.org/remotecontent?filepath=net/java/dev/jna/jna-platform/4.5.2/jna-platform-4.5.2.jar and https://search.maven.org/remotecontent?filepath=net/java/dev/jna/jna/4.5.2/jna-4.5.2.jar, adding these 2 jar files to Flyway's drivers directory and then try to connect again to see if this fixes the issue?

Works perfectly! Thank you!

Thanks for testing. Then we'll include these out of the box, starting with Flyway 5.2.
