Oh yes. Did you ever have a statement where you chain more than two method calls and don't know which returns null? I tend to split calls like this on separate lines just to be able to tell which call returns null from the line number in the stack trace. obj.call1().call2().call3(); becomes obj.call1() .call2() .call3(); And if I now get an NPE at line three, I know that call2() returned null.
