GMAPS - mapExtension.addToMap - rendering polygons with holes

There apppears to be a problem with the mapExtension class when using mapExtension.addMap to add a polygon that contains a hole. Attachment poly1.jpg shows how the displayed polygon should look and attachment poly2.jpg shows how the polygon is renedered using the following code. The image overlay from the ArcGIS Server Map service displays the polygon correctly (attachment poly3.jpg). Does anyone have a solution?

This is not a problem of the ESRI extension, it's the Google API limitation. It's v2 does not support rings with holes. However it's v3 does.
