yes it should. this is how anonymous classes work.

the work around is to pass in a locator that can be serialized without
serializing the dependency yet knows how to look it up when it is
needed. kinda like a serializable lookup. this is what wicket's
@SpringBean proxies do. the other option is to have that service
available via a static lookup.
