src/com/sun/org/apache/xerces/internal/utils/ObjectFactory.java
defines a method that parses META-INF, but the method is never called.

src/com/sun/org/apache/xalan/internal/utils/ObjectFactory.java
parses META-INF services in a way that could be replaced with a call to
java.util.ServiceLoader.

This is some cleanup & preparation for modules.
