Description

There are a lot of extensions points both on the client and server sides. Most of these pluggable APIs are configurable but the configurations they receive are not the same.

For example, Serializers, Deserializers, Partitioners, Assignors, QuotaCallbacks are passed config.originals(). On the other hand LoginModules, PrincipalBuilders and AuthenticationCallbackHandlers are passed config.values().

In practice, having access to originals() is nice as it allows to use custom configurations by simply adding it to the client/server configuration.
