While working a bit on cacio, we just found some new nice addition to the Toolkit code, like this one:
public boolean areExtraMouseButtonsEnabled() throws HeadlessException {
GraphicsEnvironment.checkHeadless();
return Toolkit.getDefaultToolkit().areExtraMouseButtonsEnabled();
}Of course, this method is meant to be overridden, so it will end up doing nothing, but things like this may be very difficult to debug at times, and in any case, is definitely are not friendly code. Is there any reason for this smartness?
Why not simply provide a default implementation or just throw an exception or simply make the method abstract? Or maybe I'm missing something?
I hope there are not many more of those examples scattered around, or to know what to subclass and override will be a pain.
Cheers, Mario
