[jax-rs-spec users] [jsr339-experts] Re: Injecting a sub-resource method path parameter into a resource field - legal or not?

btw, I'm not sure it is even in the spec now, support for injecting
JAX-RS parameter values as properties (via fields or setters), I recall
it was in 0.8 or similar and at some stage I also remember seeing the
advice about the thread safety too; as it's impossible to inject a proxy
for 'int'
