ConcurrentModificationException

[ozzi-]

Hi
After moving all static variables into a singleton, I was able to work around #14

I am using 0.17 for my Jax Jersey Project.

However, I receive the following exception when running "mvn clean install -X"
The "jaxrs-analyzer" folder is created but has no content.
