 * by a JX Swing component. ErrorEvents are only generated for internal un-recoverable errors
 * that cannot be thrown. An example would be an internal Action implementation that cannot
 * throw an Exception directly because the ActionListener interface forbids it. Exceptions
 * which can be throw directly (say from the constructor of the JX component) should not use
 * the ErrorListener mechanism.
