@Startup @Singleton @PostConstruct not called in jar with ejb-jar.xml specifying 2.x in JBoss EAP 6

Issue

• I have a Singleton class and packaged the same class in my application and deployed in standalone JBoss server. But I do not see the activate() method being called.

import javax.annotation.PostConstruct;
import javax.ejb.Singleton;
import javax.ejb.Startup;

@Startup
@Singleton
public class MySingleton {
    private Logger log = Logger.getLogger(getClass());

    @PostConstruct
    public void activate() {        
        log.info("Activate Time: " + System.currentTimeMillis() + ". Activating SystemWorkerExecutorSingleton");        
    }
}
