Description ehucka 2007-06-12 17:36:16 UTC 
Product Version: NetBeans IDE Dev (Build 070612) Java: 1.6.0_02-ea; Java HotSpot(TM) Client VM 1.6.0_02-ea-b02 System:
Linux version 2.6.16-1.2122_FC5 running on i386; UTF-8; en_US (nb)

Example:

class Bean {
 String name;
 public Bean clone() {
  Bean ret = new Bean();
  ret.name = name;
  return ret;
 }
}

The line "ret.name = name;" is annotated by warning 'Assignment To Itself'.

the same in
    public Point locationSuggested(Widget widget, Point originalLocation, Point suggestedLocation) {
        suggestedLocation.x=originalLocation.x;//<-- warning
Comment 2 Petr Hrebejk 2007-06-13 12:27:03 UTC 
Yes it will probably have many duplicates. The test is currently done by element (which is per type) and thus does not
take the variables in member selects into account.
