Are BDB SVN repositories supported? I tried pointing at one initially, and got a loooong stack trace, leading off with:

Error accessing svn org.tmatesoft.svn.core.SVNException: svn: Unable to open an ra_local session to URL

traced the error down through Google, and saw a not about JavaSVN only suporting FSFS repositories?

Berkley DB SVN repositories is currently not supported. When we support remote repositories you will also be able to access a BDB repository through the remote URL (starting with http: or svn: or similar). Remote repositories is currently planned for the next release.
