Trivial Description
I've noticed lots of NPE with the following stack trace:

The NPE is thrown because the currentNode is null in the writer, which seems to be the case when the xml document starts with a comment. Not sure why, but I suppose it should be quite easy to fix and could improve performance at start time.
