Make configuration of Liquibase’s logging more robust
We make Liquibase aware of our custom Commons Logging-based logger by adding its package to the Liquibase ServiceLocator’s packages to scan. Previously, this was happening too late so Liquibase may have already initialized and cached a particular logger. This commit moves the registration of the extra package from the Liquibase auto-configuration to the application listener that customises Liquibase’s ServiceLocator. This ensures that the package is added before Liquibase is used. Unfortunately, configuring Liquibase’s ServiceLocator and its packages to scan causes it to try to perform some logging, resulting in it caching the wrong type of logger. We work around this problem by resetting Liquibase’s LogFactory once we’ve finished setting everything up. Closes gh-6713
