Sorry, let me clarify.

The Subversion network protocol is flexible; the initial
implementation will probably be a modified form of WebDAV, in fact.

However, there's a lot more to writing a Java Subversion client than
speaking the protocol! The Subversion C client is split into three
libraries:

        * routines to manage a working copy & administrative files
        * routines to make repository filesystem calls over the
          network
        * routines for commands that use both of the other two libraries
          (such as add, commit, diff, checkout)

In addition, you'll need code that can both produce and interpret the
delta formats being transmitted back and forth. (!)

I suppose it all depends on what you want to do. A *true* native Java client
would have to implement all these things. But if you just want to do
simple network filesystem reads from the repository, then the protocol
is just about enough.
