Trying to start Bitbucket Server with Aurora MySQL fails.

Issue Summary

When trying to start Bitbucket 6.7+ with MySQL database from Aurora, it fails to state an unsupported database.

Environment

Bitbucket 6.7.0
Aurora DB MySQL

Steps to Reproduce

1. Have an instance pre-6.7 connected to Aurora MySQL (runs without issue)
2. Upgrade to 6.7.0

Expected Results

Should start without issue. Showing a warning in the logs mentioning an unsupported database.

Actual Results

Bitbucket fails to start stating:

The configured database is unsupported

Workaround

Restore to a backup from before the upgrade. Since migrating to a supported database is supported from the Database Migration wizard (and that is only accessible from the UI), you wouldn't be able to migrate after the upgrade without running a database dump and reimporting it.
