[resteasy-dev] SPI to add JAX-RS annotations dynamically

[Christian Kaltepoth]

Hi Alessio,

sorry for the delayed response. I agree that if some SPI would allow to
modify the builders, it should be done before the resource is registered in
the resource factory. Do you think such a SPI would be useful for others? I
would be happy to contribute some code if it improves portability between
RESTEasy and the MVC RI.

Thanks for pointing me to the resteasy-cdi integration. I'll have a deeper
look at it in the next days.

Christian
