In general, I will only fix a bug for you if happens to also affect me. Pokkit is a personal project that I uploaded in the hope that it will be useful to others, but I'm not willing to spend the time to create a complete, bug-free implementation of the Spigot API. See my reasoning in the README.md file.
Still, I will leave open all valid bug reports, so that anyone interested in improving Pokkit can have a look.
Contributions are very much welcomed. If you have any questions, feel free to send me an e-mail (address is on my Github profile).
In the README.md file you can find information on how to compile Pokkit. In the IMPL_EXAMPLES.md file, you can find information on how to write code for Pokkit.
Don't worry too much about code formatting, just make sure that I can read your code. Still, if you want to know: we use tabs instead of spaces for indenting, and we place opening braces ({) on the same line.
