When accessing a root resource StringIndexOutOfBoundsException is thrown

This is a stack trace, I think you need to check if a path is empty as well:

Reproduced the issue happens on Jersey on root endpoint.

I have also noticed that we have to add first / (we were stripping it) to the operation name, otherwise it will be empty which is wrong.

0.1.4 should include this fix
