Error with leader election examples

[nicolaferraro]

Simple java integration:

import org.apache.camel.builder.RouteBuilder;

public class Master extends RouteBuilder {
  @Override
  public void configure() throws Exception {
	  from("master:lock:timer:tick")
	  .setHeader("m").constant("string!")
	  .setBody().simple("Magic${header.m}")
      .log("${body}");
  }
}

When running I get:

Is it right that we have two dirs /etc/camel/config and /etc/camel/config.d ?

Directory content:
