Is this specified by the Java Virtual Machine? Can it be JVM dependent? On second thought even so this makes sense, since what is passes is a "reference". Cool anyway. Also i don't think direct comparison will work for non final and non cached classes. Just IMNHO.

The PropertyChangeSupport will handle the equivalent string case via a call to .equals(Object) An even more elegant comparison to bumper the call with the direct comparison…

public void setName( name) {
if (this.name != name) changes.firePropertyChange(”name”, this.name, this.name = name);
}

This will handle the null/null case as well as the same-string case. The PropertyChangeSupport will handle the equivalent string case via a call to .equals(Object)

It doesn't provide native property support but as a shorthand notation it's great. Yeah I use it all the time too. It doesn’t provide native property support but as a shorthand notation it’s great.

firePropertyChange(’propertyName’, null, null)

This will fire a non-change :(

I'm so used to the internal Swing code not using PropertyChangeSupport that i've missed that part. My bad.
