Just tested with tomee embedded this listener:
@ApplicationScoped
public static class Listener {
public void start(@javax.enterprise.event.Observes
@Initialized(ApplicationScoped.class) Object start) {
log(start);
}
public void end(@javax.enterprise.event.Observes
@Destroyed(ApplicationScoped.class) Object end) {
log(end);
}
private void log(final Object event) {
System.out.println();
System.out.println(this);
System.out.println(System.identityHashCode(this));
System.out.println(event);
System.out.println(System.identityHashCode(event));
System.out.println();
}
}
And got:
org.apache.tomee.embedded.ClasspathAsWebappTest$Listener@21c747a
35419258
org.apache.catalina.core.ApplicationContextFacade@77d4ac52
2010426450
org.apache.tomee.embedded.ClasspathAsWebappTest$Listener@1913053c
420676924
org.apache.catalina.core.ApplicationContextFacade@77d4ac52
2010426450
so looks good
