Hi all
I'm attempting to schedule a task from inside a singleton bean which is initialised at startup:
package foo;
import java.util.concurrent.Future;
import javax.annotation.PostConstruct;
import javax.annotation.Resource;
import javax.ejb.Singleton;
import javax.ejb.Startup;
import javax.enterprise.concurrent.ManagedExecutorService;
@Singleton
@Startup
public class StartupSingleton {
@Resource
ManagedExecutorService executorService;
@PostConstruct
public void init() {
System.out.println("init");
Future<?> future = executorService.submit(new Runnable() {
public void run() {
System.out.println("run");
}
});
try {
Thread.sleep(1000);
if(future.isDone()) {
future.get();
System.out.println("ok");
} else {
System.out.println("not run");
}
} catch (Exception e) {
e.printStackTrace();
}
}
}
I then get the following in the logs:
2014-06-10T15:45:07.497+0930|Info: init
2014-06-10T15:45:08.499+0930|Severe: java.util.concurrent.ExecutionException: javax.enterprise.concurrent.AbortedException: Module glassfish-executor-test is disabled

And the submitted task is not run. (glassfish-executor-test is just the name of the standalone test case that I created).
Surely either the executor service should be initialized and available by the time @PostConstruct stuff is executed, or it should queue submitted tasks and execute them once the application is started.
This is just using the default managed executor service in a default domain.xml file.
Ideas?
Thanks
Tom
