* <p>This class loader does not allow the users to intercept the loading

+ * of <code>java.*</code> and <code>javax.*</code> classes (and
+ * <code>sun.*</code>, <code>org.xml.*</code>, ...) unless
+ * <code>Loader.doDelegation</code> is <code>false</code>. This is because
+ * the JVM prohibits a user class loader from loading a system class.
+ * Also see Note 2.
+ * If this behavior is not appropriate, a subclass of <code>Loader</code>
