Description Erdal Karaca CLA 2012-01-23 03:08:36 EST 
If I set a custom anchor in selfStyleConnection, then, zooming does not work properly.
It seems that scaling is not applied to the coords the anchor is set to after zooming (in/out).

I will append an example to reproduce this.

I had a look at what ChopboxAnchor, an existing subclass of AbstractConnectionAnchor does and it seems you need to translate the rectangle in your implementation of getLocation(). With this in getLocation(), your example zooms fine for me:

Rectangle bounds = Rectangle.SINGLETON;
bounds.setBounds(getOwner().getBounds());
getOwner().translateToAbsolute(bounds);
