convert back to class type List from GenericEntity – anonymous class

I am getting class cast exception at line 7 in the code below. I have written line 1-3 to provide data that comes from a rest service call and these line can’t be changed from my side. I must cast the response to List

    List<Integer> lstInt = new ArrayList<Integer>();
    lstInt.add(1);
    lstInt.add(2);

    GenericEntity<List<Integer>> gEntity = new GenericEntity<List<Integer>>(lstInt) {};
    System.out.println(gEntity.getClass()); //prints com.org.dept.proj.MyClass$12
    List<Integer> output = (List<Integer>) gEntity; // class cast exception
    System.out.println(output);

Answer

Thank you @Michael. I had to run a getEntity on gEntity and then cast it as per the documentation

        List<Integer> lstInt = new ArrayList<Integer>();
        lstInt.add(1);
        lstInt.add(2);
        GenericEntity<List<Integer>> gEntity = new GenericEntity<List<Integer>>(lstInt) {};
        System.out.println(gEntity.getEntity());
        List<Integer> output = (List<Integer>) gEntity.getEntity();
        System.out.println(output);
