Returns the hash code value for this Permission object.
<P>
The required {@code hashCode} behavior for Permission Objects is
the following:
<ul>
<li>Whenever it is invoked on the same Permission object more than
once during an execution of a Java application, the
{@code hashCode} method
must consistently return the same integer. This integer need not
remain consistent from one execution of an application to another
execution of the same application.
<li>If two Permission objects are equal according to the
{@code equals}
method, then calling the {@code hashCode} method on each of the
two Permission objects must produce the same integer result.
</ul>
