GeoServer enables that support in streaming renderer, something like this:

Map<Object, Object> rendererParams = new HashMap();
rendererParams.put(StreamingRenderer.CONTINUOUS_MAP_WRAPPING, true);

and then the client code should use lontidues above 180 to request an area
crossing the dateline,
like a WMS client does... at that point it should work...

Hope this helps
