Hi,

I am the person that reported the issue. When I opened the case with Redhat support, I did indicate that changing the name solved the issue but that is not a viable workaround because we have hundreds of rest endpoints methods that start with get.

Here are all the experiments I went through and the results:
Here are all the experiments I went through to try to understand this behavior:
1. Made the bean @ApplicationScope => Exhibits the behavior explained above
2. Made the bean @Stateless => Exhibits the behavior explained above
3. Made the bean @Singleton(from the ejb package) => Exhibits the behavior explained above
4. Made the bean @Singleton @Startup => Method is only called once and after the postconstruct as expected but the return value is not validated
5. Renamed the method to not start with 'get' => Method is only called once and after the postconstruct as expected

> Having a bean class with {{@ApplicationScoped}}, which has a {{@PostConstruct}} and is implementing  the following _Interface_:
> {code}
> @Path("/validated")
> public interface ValidatedJaxRsInterface {
>     
>     @GET
>     @Valid
>     @Produces(MediaType.APPLICATION_JSON)
>     GreetingModel getHelloGreeting();
> }
> {code}
> will result in calling the {{getHelloGreeting}} method of the implementation class twice *_before_* the {{@PostConstruct}} is getting executed.
> This can be reproduced with the attached reproducer application...
