Okay, I have had a chance to look more closely at this with geoserver 2.5.1

If I have a polygon in projected coordinates, crossing the 180, then 
geoserver is doing a good job of representing it in both 4326 and in 
projected coordinates. Also working with messy fills. yeah!

I havent been able to sort out polygons with lat/long coordinates. First 
attempt got the black lines down the 180 but dumping to GML, I see that 
doing the unprojection had created multipolygon, split on the 180. My 
previously reliable method of creating 180 crossing polygons in arc 
(create in one hemisphere and shift) is also doing something odd in 
10.1. I will do more probing when I get a chance but I am very happy to 
see projected coordinates working fine.
