Mapped Diagnostic Context (MDC) with SLF4J logging in jboss/wildfly 10 it's cleared

Question

I configured my web app to use an MDC this way:

    MDC.put("cliente", "TEST");
    org.slf4j.MDC.put("cliente2", "TEST2");

Into the javax.ws.rs.core.Application startup class

import org.jboss.logging.MDC;

@ApplicationPath("/api")
public class ApplicationResource extends Application {

    public ApplicationResource(){
        MDC.put("cliente", "TEST");
        org.slf4j.MDC.put("cliente2", "TEST2");
    }

And the result in the log is:

Why my MDC it's cleared? Is necessary declare in another place?

MDC or Mapped Diagnostic Context is based on a thread local. Those other messages are written from other threads so the MDC values are not set for those messages.
