What warning are you getting?

Oh, you violated rule #0 -- NEVER put valuable information
in the subject line!

What is the declared return type for "current.getOwnedElement()"?

Collection<Element>?

as in ...

public class GenericsTest {
   public GenericsTest() {
   }

   public static void main(String[] args) {
     GenericsTest test = new GenericsTest();
     Current current = new Current();
     ArrayList<Element> children = new ArrayList<Element>();
     children.addAll(current.getOwnedElement());
   }

   public static class Current {
     public Collection<Element> getOwnedElement() {
       return null;
     }
   }
}

Your choice of names seems odd: "ownedElement" doesn't
connote a collection required by "addAll".  "ownedElements"
would seem to be more appropriate.
