That does look fishy.
"result" will be ignored if currentCL.getParent returns non-null. If
currentCL.getParent returns null, then the method throws an exception.
It looks like this could be re-written in a more straightforward way
like this:
currentCL = currentCL.getParent();
if(null == result && null == currentCL)
throw new IllegalArgumentException(...);
while(currentCL != null)
// continue
Of course, you still need to check for null after the loop, so it's
not like the change really affects anything other than minor readability.
