> PermissionResolvers are seam components, and the documentation doesn't mention any restrictions on them.  However, because PermissionMapper caches the resolver chain in the application, and doesn't serialize access to the resolvers themselves, PermissionResolvers must not only be stateless but also must not use injections, even of stateless components,  as bijection on each resolver might be interlaced from multiple threads.  
> This should probably be documented, as it just exposed itself as on our production server as nasty errors under load :)
