It seems that locking (synchronized blocks) the registerServices field within the RemoteServiceRegistry is involved with this issue.
Comment 1 Stefan Liebig CLA 2011-05-09 08:02:23 EDT 
The synchronized blocks have been removed and the registeredServices map is wrapped with Collections.synchronizedMap().
