To test the network connection might not always be appropriate, because
it's possible to have a local subversion repository without http access
(using the svn:// or the file:// protocol).

Maybe we could catch and handle the execption like this:

try {
  do svn up
} catch (SVNException e) {
  if (e.getErrorMessage().gerErrorCode() == SVNErrorCode.RA_DAV_REQUEST_FAILED) {
    log.warn("svn repository not available: entering offline mode");
    isOffline = true;
  } else {
    throw e; // cannot recover
  }
}

WDYT?
