+/**
+ * In order to run the example we need set the -agent parameter to the JVM but Play have some limitations when trying to set an
+ * java agent in Play dev mode (ie, play run) -> https://github.com/playframework/playframework/issues/1372, so we have others options:
+ *
+ * The first option is set -javaagent: path-to-aspectj-weaver in your IDE or
+ *
+ * Run the following commands from console:
+ *
+ * 1- play stage
+ * 2- cd target/universal/stage
+ * 3- java -cp ".:lib/*" -javaagent:lib/org.aspectj.aspectjweaver-1.8.1.jar play.core.server.NettyServer
+ *
+ * and finally for test:
+ *
+ * curl -i -H 'X-Trace-Token:kamon-test' -H 'MyTraceLocalStorageKey:extra-header' -X GET "http://localhost:9000/helloKamon"
+ *
+ * we should get:
+ * HTTP/1.1 200 OK
+ * Content-Type: text/plain; charset=utf-8
+ * MyTraceLocalStorageKey: extra-header -> Extra Information
+ * X-Trace-Token: kamon-test -> default Trace-Token
+ *
+ * Say hello to Kamon
