Questions about asynchronous invocation

[Jose María Zaragoza]

Hello:

I'm using Apache CXF 2.7.8 and I've got a questions about asynchronous
invocation:


1) When I use a standalone client with the next code :

//
 Future<?> future = client.sendAsync(request, new EmailAsyncHandler());

 while (!future.isDone())
 {
     System.out.println("Waiting ...");

}
System.out.println("Done");


the JVM process never is finished although "Done" log is printed

About jvisualm , there is a thread running

java.lang.Thread.State: RUNNABLE

I know that I can do System.exit(0) , but I wonder why if Future
object is done , Thread is not finished. What is the reason ? How I
can finish this thread ? Could be a problem if asynchronous client is
executed in a web container ?



2) I'm using @UseAsyncMethod annotation in synchronous method signature like

@UseAsyncMethod
public EmailResponse send(EmailRequest emailRequest)

but asynchronous implementation like

public Future<?> sendAsync(EmailRequest emailRequest,
AsyncHandler<EmailResponseWrapper> sendHandler)

is never invoked , did I forget something ?

I using cxf-rt-transports-http-hc module


Thanks and regards
