/**

 * An {@code Error} is a subclass of {@code Throwable}

 * that indicates serious problems that a reasonable application

 * should not try to catch. Most such errors are abnormal conditions.

 * The {@code ThreadDeath} error, though a "normal" condition,

 * is also a subclass of {@code Error} because most applications

 * should not try to catch it.

 * <p>

 * A method is not required to declare in its {@code throws}

 * clause any subclasses of {@code Error} that might be thrown

 * during the execution of the method but not caught, since these

 * errors are abnormal conditions that should never occur.

 *

 * That is, {@code Error} and its subclasses are regarded as unchecked

 * exceptions for the purposes of compile-time checking of exceptions.
