I have a problem with asynchronous get operation in Ispn-6.0.2. I am using it like this to read a set of values based on their IDs:

        for (String string : ids) {

            cache.getAsync(string).attachListener(new FutureListener<MyClass>() {

                @Override

                public void futureDone(Future<MyClass> future) {

                    try {

                        queue.put(future.get());

                    } catch (InterruptedException | ExecutionException | NullPointerException ignore) {     }

                }               

            });

        }

When I start to use it more heavily (hundreds of simultaneous reads) it happens to me that (probably all) the reading threads (transport-thread-0  to  -24) got stuck in the "future.get()" method with this stack trace:

Hidden Source Calls (Unsafe.park)

LockSupport.park:186

AbstractQueuedSynchronizer.parkAndCheckInterrupt:834

AbstractQueuedSynchronizer.doAcquireSharedInterruptibly:994

AbstractQueuedSynchronizer.acquireSharedInterrptibly:1303

FutureTask$Sync.innerGet:248

FutureTask.get:111

NotifyingFutureAdaptor.get:44

MyClassMethod$2.futureDone:113

I understand it like this: the async read was finished because the .futureDone method was called, but the method cannot get to the result from "Future", which is very strange...

Do you have any suggestions what I could do about it? Thank you very much.
