[resteasy-dev] CDI stereotype usage in JAX-RS annotated methods

[Martin Stefanko]

I think the idea is that user can group a few JAX-RS annotations together
and apply them on more than one resource with the stereotype annotation
instead of copy-pasting them every time [1]. But sure, in the issue example
case it does not simplify anything.
