One of our Customers found a situation where config file updates are not immediately picked up by the Liferay platform without a server restart. The situation/s when a server restart is needed to apply config file updates is not clear from our documentation:
David Nebinger mentioned on Loop that the @Modified notation is needed in a component to apply config file changes during runtime. Otherwise, a restart is needed. This information (and anything else that explains when a server restart is needed to pick up config file changes) would be useful in official documentation.
