I get an exception on the following document:

* [Developing a Nifi custom processor](https://github.com/aperepel/nifi-workshop) Removing the space between the * and the [ solves the exception.

This is the traceback:

The problem is in RecommonMark library. In master there is M2R convertor as another MarkDown parser, which is much better then RecommonMark. Fix will be released in next minor version.
