Versions used

JDK: 1.8.0 update 40
NetBeans IDE: 8.0.2
MySQL: 5.6.23
Tomcat: 8.0
Spring: 4.1.5
Hibernate: 4.3.8.Final
Flyway: 3.2.1

Known issues & quirks:

If language switch (?lang=X) is applied right after an entity change action (edit/add), the view will jump back to the previous edit/add page. This is because after action, the URL is left unchanged (no redirect: used) eg the previous target page, while the controller actually returns the home page after action.
If language switch (?lang=X) is applied right after a DELETE action, a 500 error (NullPointerException) occurs since the delete URL with an id of already deleted entity gets resubmitted. Thus, delete action reoccurs on an object which doesn’t exist anymore.
