Re: Need for jsk-dl.jar

I'm slogging through classes and jars attempting some modularization of the 
River codebase. Its going fairly well. I'm sitting here scratching my head 
whilst looking at jsk-dl.jar. My question is as follows:

In general jsk-lib.jar is either in the classpath of a service, as well as in 
the classpath of a client. The inclusion of jsk-lib.jar (from a client's point 
of view) brings along helpful utilities like ServiceDiscoveryManager and the 
like. From a service developers point of view, you can't really get around not 
using it.

If jsk-lib.jar is in the classpath (and by inclusion jsk-platform.jar), why do 
we need jsk-dl.jar? Unless I'm mistaken all of the classes that are in 
jsk-dl.jar are already in jsk-lib.jar, why is it needed?

What have I forgotten?

I was alluding to that earlier myself, it seems to be there for proxy's to utilise when clients lack jsk-lib.jar, but in a modular environment this could cause versioning issues, if the client already has it installed locally, the release notes simply states:
The codebase JAR file for |jsk-lib.jar|. An application that includes |jsk-lib.jar| in its class-path may also need to include |jsk-dl.jar| in its codebase.
Oddly enough a diff reveals that there is one class present in jsk-dl.jar missing from jsk-lib.jar:
