042 * Applications should not try to catch errors since they indicate
043 * abnormal conditions.  An abnormal condition is something which should not
044 * occur, or which should not be recovered from.  This latter category
045 * includes <code>ThreadDeath</code> and <code>AssertionError</code>.
046 *
047 * <p>A method is not required to declare any subclass of <code>Error</code> in
048 * its <code>throws</code> clause which might be thrown but not caught while
049 * executing the method.
