title: Lombok @Getter and copies of Collections
body: <p>Using <code>@Getter</code> on a <code>List</code> field works fine, but on attempting to upgrade to Java 8 I encounter <code>ConcurrentModificationException</code>s because the getter generated by Lombok does not perform a copy of the field, which is essential should you wish to prevent external modification of the instance's state.</p>
  
  <p>Any ideas how I can get Lombok to copy the <code>Collection</code> on getters, or am I restricted to writing my own?</p>
