Deadlock in RemoteCache getAsync -------------------------------- Key: ISPN-3868 URL: https://issues.jboss.org/browse/ISPN-3868 Project: Infinispan Issue Type: Bug Components: Core API Affects Versions: 6.0.0.Final Environment: RemoteCahe component of 6.0.0.Final Reporter: Alexander Furer Assignee: Mircea Markus Priority: Critical Labels: remote Here is the implementation of remoteCahe.getAsync() : {code} public NotifyingFuture<V> getAsync(final K key) { assertRemoteCacheManagerIsStarted(); final NotifyingFutureImpl<V> result = new NotifyingFutureImpl<V>(); Future<V> future = executorService.submit(new Callable<V>() { @Override public V call() throws Exception { V toReturn = get(key); result.notifyFutureCompletion(); return toReturn; } }); result.setExecuting(future); return result; } {code} 2 problems here : 1. Callable's call method might be called BEFORE calling client had a chance to add listener (i.e. getAsync is not returned yet), in this case its' listener futureDone method will never be called. 2. Even case #1 has not happened and notifyFutureCompletion is called on listener, but the future is not resolved yet : "call" has not returned, that's why the future that is passed to listener is not resolved, and calling future.get from listener blocks forever.
