Description Thomas Segismont 2013-04-30 15:27:22 UTC 
Description of problem:
Using Singleton bean PreDestroy callback is a common way to perform tasks when server goes down. But calling Stateless bean methods in the callback code fails with the following error:

javax.ejb.EJBException: JBAS014559: Invocation cannot proceed as component is shutting down 

Version-Release number of selected component (if applicable):
EAP 6.1

How reproducible:
Always

Steps to Reproduce:
1. Start EAP 6.1 and deploy an application with a Singleton bean calling a Stateless bean method in its PreDestroy callback
2. Stop EAP 6.1
  
Actual results:
Server shows an error "javax.ejb.EJBException: JBAS014559: Invocation cannot proceed as component is shutting down" and stops

Expected results:
Server calls Stateless bean method and stops.

As explained in an internal mail thread, you'll have to add a @DependsOn annotation on the singleton bean to depend on the stateless bean:

@Singleton
@Startup
@javax.ejb.DependsOn("StatelessBean") // depend on the stateless bean
public class SingletonBean {

....
  @PreDestroy
    public void shutdown() {
        System.out.println("###############################");
        System.out.println("SingletonBean.shutdown");
        System.out.println("###############################");
        statelessBean.doSomething();
    }
}
