Add the annotation @suppresswarnings("unchecked") to the method (or class if you want it to be global for that class) declaration.
E.g. turn
-------------------
public void aMethod(List list) {
  Collections.sort(list);
}
-------------------
into
-------------------
@suppresswarnings("unchecked")
public void aMethod(List list) {
  Collections.sort(list);
}
-------------------

I'm not fond of annotations, but this is one case they could come in handy (though of course it's like shooting a moquito with an elephant gun as you're potentially hiding warnings you do want to soo).
