When a JdbcPlugin is instantiated, creating an instance of a module at that time causes the instance to be shared by all connectors provided by the plugin. This is problematic when the module extends AbstractConfigurationAwareModule, as it holds a reference to the ConfigurationFactory, which is set dynamically during bootstrap. If catalogs are loaded concurrently, this can lead to situations where a connector accesses the configuration of another connector.
