Igor Vaynberg resolved WICKET-1403.
-----------------------------------

       Resolution: Fixed
    Fix Version/s: 1.4-RC2
                   1.3.6
         Assignee: Igor Vaynberg  (was: Alastair Maw)

removed typestore

guiceproxytargetlocator now keeps all the information necessary to resolve the type. should now work fine in the cluster as well.

the only interesting thing is that it keeps a ref to java.lang.Annotation which does not extend serializable yet no error is caused. i am guessing sun's annot impl is serializable. should possible fix this later.
