Two reasons:
1. Using java.lang.Object will make ModSAX Java-dependent.
2. Using ModHandler interface adds some compile-time type-check.
Only penalty is increasing the number of interfaces a class implements which
does affect the performance during runtime. Very little penalty in most
cases.
<java_tip>
Most Java VM implementations search the interface list back to front so that
most often used interface (i.e. org.w3c.dom.Node) should be the last
interface in the 'implements' list.
