<div class="block">An <code>Error</code> is a subclass of <code>Throwable</code>
that indicates serious problems that a reasonable application
should not try to catch. Most such errors are abnormal conditions.
The <code>ThreadDeath</code> error, though a "normal" condition,
is also a subclass of <code>Error</code> because most applications
should not try to catch it.
<p>
A method is not required to declare in its <code>throws</code>
clause any subclasses of <code>Error</code> 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</code> and its subclasses are regarded as unchecked
exceptions for the purposes of compile-time checking of exceptions.</div>
