This class defines a classloader that "merges" multiple classloaders. For this to be successful, it is required that the ClassLoaders contain disjoint sets of classes (with the exception of classes loaded from the system classpath). @author Peter Donald @version $Revision: 1.1 $ $Date: 2004/04/19 22:19:25 $
