finally added in jdk1.6 (thank god!!!!!!!!!!)
-Dsun.io.serialization.extendedDebugInfo=true
and I had spent years in pain without this in previous jdk versions :(, but now I can see seam is clustering a hell of alot of stuff I don't want it too. Now comes trying to clean it all up with a much easier message(it gives the whole object graph of serialization ...it's sweeet).
