String type is immutable, meaning if you are holding on a reference to it, it will never be changed even it is "modified" since a new object/reference will be created.
List type is not immutable, regardless of if it is used in an JPA Entity, either managed or detached. Not sure exactly what you are looking for but an example may be helpful here.
