CDI version of EJB Singleton?

[Matthew Broadhead <ma...@nbmlaw.co.uk>]

Hi,
I have converted most of my old EJB stuff to CDI but the one thing that 
is still using EJB are these @Asynchronous @Singleton things. Please 
could anyone provide a "CDI way" example to accomplish the same result?

import javax.ejb.AccessTimeout;
import javax.ejb.Asynchronous;
import javax.ejb.Lock;
import javax.ejb.LockType;
import javax.ejb.Singleton;

@Singleton
public class SomethingAsync {

     @Asynchronous
     @Lock(LockType.READ)
     @AccessTimeout(-1)
     public void addJob(String value) {
         // this job takes a while
         doSomething(value);
     }

     public void doSomething(String value) {
        System.out.println(value);
     }
}

Hi Matthew,

DeltaSpike has this feature but it is not built-in in the spec:
