The correct value should be
 <property name="DefaultMapArea">
                <object class="ucar.unidata.geoloc.ProjectionRect">
                    <constructor>
                        <double>-3718.9811314976646</double>
                        <double>-1318.7048434428925</double>
                        <double>2559.253047605616</double>
                        <double>4959.529335660388</double>
                    </constructor>
                </object>
            </property>

but, somehow, running 4.1 these values mysteriously changed. Don't know why.
