From the developer preview relnotes (should be ok to post this  
extract since the product is now released):
Java SE 5.0 graphics renderer defaults to Quartz

Due to a number of unaddressable performance and fidelity issues with  
the Sun2D renderer in Java SE 5.0, the default graphics renderer has  
been switched back to Quartz. In Java SE 6, the quality and the  
performance of the Sun2D renderer is significantly better, so the  
default renderer for Java SE 6 will remain Sun2D.

To choose between the Quartz and Sun-based renderers, use the boolean  
System Property apple.awt.graphics.UseQuartz. This property is set  
appropriately based on the renderer that is in use. Setting the  
property after the instantiation of the AWT has no effect on which  
renderer is used.
