Embeddable distributed version control system in Java?

dvcs, java

Solution

@Josh Moore's reply led me to JGit, which seems to be a competitor to JavaGit. JGit is pure Java and licensed under BSD.

Some further digging unearthed HgKit, which aims to implement Mercurial in Java. It is still pre-alpha and GPLed.

Problem

Is there a distributed version control system (like git or Mercurial) that can be used as an embedded library in Java applications (to implement versioned and synchronizable storage for application data), ideally written in pure Java and under a permissive license?
