/**
 * Constructs a ModelMBeanInfoSupport which is a duplicate of the given
 * ModelMBeanInfo.  The returned object is a shallow copy of the given
 * object.  Neither the Descriptor nor the contained arrays
 * ({@code ModelMBeanAttributeInfo[]} etc) are cloned.  This method is
 * chiefly of interest to modify the Descriptor of the returned instance
 * via {@link #setDescriptor setDescriptor} without affecting the
 * Descriptor of the original object.
 *
 * @param mbi the ModelMBeanInfo instance from which the ModelMBeanInfo
 * being created is initialized.
