Thanks for posting the stack trace. I'm looking into it now.

Would you mind sharing the class you are using this library in? It will help me understand the cause.

[denley]

Actually, I've managed to reproduce it. It happens when you use the library in an abstract class with an abstract method.

[denley]

I've just released version 3.0.1, which includes a fix for this issue.

Please reopen this issue if you find that it's still not fully fixed yet.

Confirming the issue is fixed, builds with no errors.
Thanks for the quick response and nice work!
