[infinispan-issues] [JBoss JIRA] (ISPN-6392) Convert NotifyingFuture and friends to CompletableFuture

Convert NotifyingFuture and friends to CompletableFuture -------------------------------------------------------- Key: ISPN-6392 URL: https://issues.jboss.org/browse/ISPN-6392 Project: Infinispan Issue Type: Enhancement Components: Core Reporter: William Burns Assignee: William Burns Fix For: 9.0.0.Final, 9.0.0.Alpha1 Now that we have Java 8 we should be using standard classes as much as possible. Before we had special future instances to handle callbacks and we should change all of these to use CompletableFuture instead so the API is what users would be used to.
