Notes on operation of an asynchronous method

You cannot execute the method cancellation functionality in a Session Bean that executes the asynchronous invocation, if you try to cancel the method, the KDJE52703-W message is output; however, the method is not cancelled.
To cancel the asynchronous method, use a method of the Future<V> object.
When the application stops, cleanup processing is executed. Cleanup processing does not end until all the running processes end. When all the processes are complete, cleanup processing ends and the application stops.
If you invoke the asynchronous processing of a Session Bean by using a remote interface, an object which causes full garbage collection during the server operation, is generated. Therefore, if you want to prevent the occurrence of a full garbage collection, use the remote interface and do not invoke the asynchronous processing.
