How can I get the name of a user and affected branches in a BitBucket pre-receive hook?

Question

I've got a pre-receive BitBucket hook written using the Java API which does some analysis on diffs or file contents. It works perfectly thus far. I would like to be able to get the name or username of the user who pushed the changes, as well as the branch to which the changes were pushed. Is this possible? I would have imagined that this metadata would be available as part of a ref or changeset, but from what I have seen thus far in the javadocs, it does not appear to be.

Thanks!

The branch name:

changeRef.getRef().getDisplayId();

(or getId() if you don't mind the name starting with "refs/heads/").

The current user:

ApplicationUser u = authenticationContext.getCurrentUser();

Spring-inject a com.atlassian.bitbucket.auth.AuthenticationContext (from bitbucket-api.jar) to get your hands on one of those.
