Description

isInLatestSnapshot() may return true in cases where an inode's ancesstors might not be in the latest snapshot.

// if parent is a reference node, parent must be a renamed node. We can 
// stop the check at the reference node.
if (parent != null && parent.isReference()) {
  // TODO: Is it a bug to return true?
  //       Some ancestor nodes may not be in the latest snapshot.
  return true;
