      Oracle JDK 7, Linux Fedora 18 64-bit, Eclipse Kepler m6


      I am running a simple .war file under Glassfish 4.0-b87 that was created in Eclipse Kepler M6 using M2E as a simple project with Dynamic Web Module facet added, using Oracle Java 7 JDK/JVM.

      There is essentially a single class for which I expect the `post_construct` method to be called exactly once. But it is called twice, first when the app is deployed, and one more time on the first and only the first HTTP request.

      Here is the class (the log output follows). It should print "hello world" only once but in the log it can be seen twice.

          package com.example.main;
          import javax.annotation.PostConstruct;
          import javax.annotation.PreDestroy;
          import javax.ejb.LocalBean;
          import javax.ejb.PostActivate;
          import javax.ejb.PrePassivate;
          import javax.ejb.Singleton;
          import javax.ejb.Startup;
          import javax.enterprise.inject.spi.PassivationCapable;
          public class Life extends Application implements PassivationCapable {
            public void post_construct () {
              System.out.println("hello world!");
            public void pre_destroy () {
              System.out.println("so long and thanks for the fish!");
            public void pre_passivate () {
              System.out.println("taking a break");
            public void post_activate () {
              System.out.println("back from break");
            public String getId () {
              return "life";
            public String greet () {
              return "hi";

      The log output is as follows with a dashed line separating the part before the first HTTP call and the part after the HTTP call:
