* Define a descriptive message to be reported.  In the most common
* usage, the message is just a <code>String</code>.  However, the type

* its type:
* <dl compact>
* <dt><code>Object[]</code><dd> A recursively interpreted series of messages.
* <dt>{@link Component}<dd> The <code>Component</code> is displayed in the dialog.
* <dt>{@link javax.swing.Icon}<dd> The <code>Icon</code> is wrapped in a {@link JLabel} and displayed in the dialog.
* <dt>anything else<dd> The {@link Object#toString string representation} of the object.
* </dl>
