Asynchronous run in the default thread pool (can be changed), and is restricted to EJB.
A ManagedExecutorService can be configured (min and max number of threads, idle time, hung time, etc), and allows submitting Runnables and Callables.
By configuring a ManagedExecutorService you can have more control over the execution when it comes to the number of concurrent tasks running in parallel, keeping the number of utilized resources (Data Base connections mostly) under control.
