Once upon a time, there was a commons sandbox project that held all
sorts of small interfaces just like this one. It was called commons-pattern.
It didn't suceed, because these interfaces really need to be provided by
the JDK and implemented by all the JDK classes to be successful. Beyond
that
Please pick another name, whatever else you do. JAXB uses ObjectFactory.

Let me draw an analogy with Adoby Flex:
There is an IFactory interface that servers for the same purpose and is
quite useful.
The problem it solves is the following:
Typically (in Flex) object initialization is not only constructor
invocation, but also setting certain properties and invoking diff
This interface seems so generic as to be difficult to understand what the
motivation is.
I can see the point of a one method interface like Comparable, but how does
ObjectFactory help? Is your goal documentation? Name standardization?
Reflection marker?

With Java 1.5 it is possible to define a generic interface for creating
an object:
public interface ObjectFactory {
T create();
}
This is a proposal to add such an interface to [lang] 3.0 with a couple
of default implementations, e.g.
- a ConstantObjectFactory returning always the same co
