Description Jesse Glick 2009-02-18 20:22:40 UTC 
The icon editor which picks an icon from a project creates bad code:

  new ImageIcon(getClass().getResource(...))

This is unsafe because a subclass of the form class in a different package will throw an NPE trying to load this icon.
The code should read

  new ImageIcon(ThisClass.class.getResource(...))
Comment 1 Jesse Glick 2009-02-18 20:33:01 UTC 
Since it uses an absolute icon path, a subclass would still be able to load the icon even if it were in a different
package, and probably even if in a different class loader (unless package restrictions are in effect). Still poor style
and may trigger warnings from code style checkers looking for getClass().getResource("relative") which is always wrong.
