Hi there Thanks for raising this. Can you create a JIRA for this here: https://issues.apache.org/jira? If you want to have a go at the fix, just let us know and submit either a patch attached to the JIRA issue or a pull request through GitHub. If not, I'll happily pick this up and fix.
We've had a few fixes on the 1.7.x branch now, so we could look at rolling a new release pretty soon.
