Deploying a Web application in WildFly 28.0.0, let's assume the following JAX-RS resource class:
 
@Path("debug")

public class DebugResource {

@POST

public void create(@Valid User user) {

...

}

{color:#000000}}

 
When a POST request is executed, the User parameter is validated twice.
It seems that Jakarta CDI container, which uses proxies, may be the source
of this unexpected behavior as, at least, two instances will be created:
* DebugResource$Proxy$_$$_WeldClientProxy

• DebugResource$Proxy$_$$_WeldSubclass
   
  Could this be a bug?
