      According to JAXRS specification : "As a general rule, for each JAX-RS component class there can be at most one registration — class-based or instance-based — configured at any given moment. Implementations MUST reject any attempts to configure a new registration for a provider class that has been already registered in the given configurable context earlier. Implementations SHOULD also raise a warning to inform the user about the rejected component registration. "
