Provides the classes which implement advanced dynamic loading. See the chapter Advanced Dynamic Loading in the JMX Specification.

An MBean that is of a subclass of {@link java.lang.ClassLoader} can be used as a class loader to create other MBeans via the method {@link javax.management.MBeanServer#createMBean(String, ObjectName, ObjectName, Object[], String[])}, and to instantiate arbitrary objects via the method {@link javax.management.MBeanServer#instantiate(String, ObjectName, Object[], String[])}. The {@link javax.management.loading.MLet MLet} class is an example of such an MBean. It is a {@link java.net.URLClassLoader URLClassLoader}, so the list of URLs to load classes from can be configured.

Additionally, an `MLet` can read a configuration file that specifies a set of MBeans to be registered in the same MBean Server as the `MLet`.

Every MBean Server has a class loader repository containing all MBeans registered in that MBean Server that are of a subclass of {@link java.lang.ClassLoader}. The class loader repository is used by the forms of the `createMBean` and `instantiate` methods in the {@link javax.management.MBeanServer MBeanServer} interface that do not have an explicit loader parameter. It is also used by the `MLet` class when it does not find a class in its own set of URLs.

If an MBean implements the interface {@link javax.management.loading.PrivateClassLoader PrivateClassLoader}, then it is not added to the class loader repository. The class {@link javax.management.loading.PrivateMLet PrivateMLet} is a subclass of `MLet` that implements `PrivateClassLoader`.
