 * support. Since UIMA Exceptions are internationalized, the thrower does not supply a hardcoded
 * message. Instead, the thrower specifies a key that identifies the message. That key is then
 * looked up in a locale-specific {@link java.util.ResourceBundle ResourceBundle} to find the actual
 * message associated with this exception.
 * <p>
 * The thrower may specify the name of the <code>ResourceBundle</code> in which to find the
 * exception message. Any name may be used. If the name is omitted, the resource bundle identified
 * by {@link #STANDARD_MESSAGE_CATALOG} will be used. This contains the standard UIMA exception
 * messages.
