+
+    <p>If an MXBean uses custom mappings, then an MXBean proxy for

+      This requires more careful synchronization between client and
+      server than is necessary with the default mappings.  For example
+      it typically requires the client to have the same implementation
+      of any {@link MXBeanMapping} subclasses as the server.  For this
+      reason, custom mappings should be avoided if possible.</p>
+
+    <p>Every MXBean has an associated {@link MXBeanMappingFactory}.
+      Call this <code><em>f</em></code>.  Then every type that appears
+      in that MXBean has an associated {@link MXBeanMapping}
+      determined by <code><em>f</em></code>.  If the type is
+      <code><em>J</em></code>, say, then the mapping is {@link
+      MXBeanMappingFactory#mappingForType
+      <em>f</em>.mappingForType}<code>(<em>J</em>,
+      <em>f</em>)</code>.</p>
+

+          or to the {@link JMX#newMXBeanProxy JMX.newMXBeanProxy}
+          method, and the {@code MBeanOptions} object defines a non-null
+          {@code MXBeanMappingFactory}, then that is the value of
+          <code><em>f</em></code>.</p></li>
+
+      <li><p>Otherwise, if the MXBean interface has an {@link
+          MXBeanMappingFactoryClass} annotation, then that annotation
+          must identify a subclass of {@code MXBeanMappingFactory}
+          with a no-argument constructor.  Then
+          <code><em>f</em></code> is the result of calling this
+          constructor.  If the class does not have a no-argument
+          constructor, or if calling the constructor produces an
+          exception, then the MXBean is invalid and an attempt to
+          register it in the MBean Server will produce a {@link
+          NotCompliantMBeanException}.</p>
+
+        <p>This annotation is not inherited from any parent
+          interfaces.  If an MXBean interface has this annotation,
+          then usually any MXBean subinterfaces must repeat the same
+          annotation for correct behavior.</p></li>
+
+      <li><p>Otherwise, if the package in which the MXBean interface
+          appears has an {@code MXBeanMappingFactoryClass} annotation,

+ *
+ * <p>This is not a valid type for MXBeans, because it contains a

+ * MXBean interface contains {@code MyLinkedList}, that will be mapped
+ * into a {@code String[]}, which is a valid Open Type.</p>
+ *
+ * <p>To define this mapping, we first subclass {@code MXBeanMapping}:</p>
+ *
+ * <pre>
+ * public class MyLinkedListMapping extends MXBeanMapping {
+ *     public MyLinkedListMapping(Type type) throws OpenDataException {
+ *         super(MyLinkedList.class, ArrayType.getArrayType(SimpleType.STRING));

+ *     public Object fromOpenValue(Object openValue) throws InvalidObjectException {
+ *         String[] array = (String[]) openValue;
+ *         MyLinkedList list = null;
+ *         for (int i = array.length - 1; i &gt;= 0; i--)
+ *             list = new MyLinkedList(array[i], list);
+ *         return list;
+ *     }
+ *
+ *     {@literal @Override}
+ *     public Object toOpenValue(Object javaValue) throws OpenDataException {

+ *              list = list.getNext())
+ *             array.add(list.getName());
+ *         return array.toArray(new String[0]);
+ *     }
+ * }
+ * </pre>
+ *
+ * <p>The call to the superclass constructor specifies what the
+ * original Java type is ({@code MyLinkedList.class}) and what Open
+ * Type it is mapped to ({@code
+ * ArrayType.getArrayType(SimpleType.STRING)}). The {@code

+ * String[]}) to the Java type ({@code MyLinkedList}), and the {@code
+ * toOpenValue} method says how we go from the Java type to the Open
+ * Type.</p>
+ *
+ * <p>With this mapping defined, we can annotate the {@code MyLinkedList}
+ * class appropriately:</p>
+ *
+ * <pre>
+ * {@literal @MXBeanMappingClass}(MyLinkedListMapping.class)
+ * public class MyLinkedList {...}
+ * </pre>
+ *
+ * <p>Now we can use {@code MyLinkedList} in an MXBean interface and it
+ * will work.</p>

+ *
+ * <p>Consider the {@code MyLinkedList} example from the {@link MXBeanMapping}

+ * This includes types such as {@code MyLinkedList[]} and

+ * invoke {@code MyLinkedListMappingFactory} to map the contained
+ * {@code MyLinkedList} type.</p>
+ *
+ * <p>Once we have defined {@code MyLinkedListMappingFactory}, we can use
