svn commit: r645211 - /xerces/java/trunk/samples/xni/ObjectFactory.java

Log:
If an application wants to clear a property they're out of luck unless
they use Java 5.0 or above (see System.clearProperty()). The closest
thing they can do is set the value to the empty string. Instead of
making a futile attempt to create an instance of a class named "" we
treat it as if it were null (i.e. cleared) and then move on to the
next step in the factory lookup.
