/**
* Mark an Entity or a Collection as immutable. No annotation means the element is mutable.
*
* An immutable entity may not be updated by the application. Updates to an immutable
* entity will be ignored, but no exception is thrown. @Immutable must be used on root entities only.
*
*
* @Immutable placed on a collection makes the collection immutable, meaning additions and
* deletions to and from the collection are not allowed. A HibernateException is thrown in this case.
