/**
 * <p>Instances of this interface are used to keep the list of ClassLoaders
 * registered in an MBean Server.
 * They provide the necessary methods to load classes using the registered
 * ClassLoaders.</p>
 *
 * <p>The first ClassLoader in a <code>ClassLoaderRepository</code> is
 * always the MBean Server's own ClassLoader.</p>
 *
 * <p>When an MBean is registered in an MBean Server, if it is of a
 * subclass of {@link java.lang.ClassLoader} and if it does not
 * implement the interface {@link PrivateClassLoader}, it is added to
 * the end of the MBean Server's <code>ClassLoaderRepository</code>.
 * If it is subsequently unregistered from the MBean Server, it is
 * removed from the <code>ClassLoaderRepository</code>.</p>
 *
 * <p>The order of MBeans in the <code>ClassLoaderRepository</code> is
 * significant.  For any two MBeans <em>X</em> and <em>Y</em> in the
 * <code>ClassLoaderRepository</code>, <em>X</em> must appear before
 * <em>Y</em> if the registration of <em>X</em> was completed before
 * the registration of <em>Y</em> started.  If <em>X</em> and
 * <em>Y</em> were registered concurrently, their order is
 * indeterminate.  The registration of an MBean corresponds to the
 * call to {@link MBeanServer#registerMBean} or one of the {@link
 * MBeanServer}<code>.createMBean</code> methods.</p>
