033:         * Subclass of <code>AbstractReflectiveMBeanInfoAssembler</code> that allows for
034:         * the management interface of a bean to be defined using arbitrary interfaces.
035:         * Any methods or properties that are defined in those interfaces are exposed
036:         * as MBean operations and attributes.
037:         *
038:         * <p>By default, this class votes on the inclusion of each operation or attribute
039:         * based on the interfaces implemented by the bean class. However, you can supply an
040:         * array of interfaces via the <code>managedInterfaces</code> property that will be
041:         * used instead. If you have multiple beans and you wish each bean to use a different
042:         * set of interfaces, then you can map bean keys (that is the name used to pass the
043:         * bean to the <code>MBeanExporter</code>) to a list of interface names using the
044:         * <code>interfaceMappings</code> property.
045:         *
046:         * <p>If you specify values for both <code>interfaceMappings</code> and
047:         * <code>managedInterfaces</code>, Spring will attempt to find interfaces in the
048:         * mappings first. If no interfaces for the bean are found, it will use the
049:         * interfaces defined by <code>managedInterfaces</code>.
