As of version 1.0-b09 it is not possible anymore to pass Endpoint instances to DefaultServerConfiguration objects. This makes it impossible to pass Endpoint instances to a server. Currently it is only possible to provide the server with Endpoint classes which then get instantiated by the server. This is problematic in situations where Endpoints need to be configured before being deployed.
If it is not intended to pass Endpoint instances to the ServerConfiguration, the user should be able to register objects that take care of Endpoint instantiation or configuration after instantiation by the server.
