protected Object clone() throws CloneNotSupportedException  {
        return (super.clone());
    }
Returns a new <code>RowSet</code> object containing by the same data
as this <code>CachedRowSetImpl</code> object.  This method
differs from the method <code>createCopy</code> in that it throws a
<code>CloneNotSupportedException</code> object instead of an
<code>SQLException</code> object, as the method <code>createShared</code>
does.  This <code>clone</code>
method is called internally by the method <code>createShared</code>,
which catches the <code>CloneNotSupportedException</code> object
and in turn throws a new <code>SQLException</code> object.

@return a copy of this <code>CachedRowSetImpl</code> object
@throws CloneNotSupportedException if an error occurs when
attempting to clone this <code>CachedRowSetImpl</code> object
