Hi Mark, thank you for your advice, I don't know too much about licenses. I have just changed the license to Apache-2.0, hope that this will be ok, and make things easier.
If you need any help or have some comments about the implementation, please let me know. I would be really happy if this implementation is finally integrated into Lucene.
