Distributed executor does not fail over unless future.get() is called --------------------------------------------------------------------- Key: ISPN-7470 URL: https://issues.jboss.org/browse/ISPN-7470 Project: Infinispan Issue Type: Bug Components: Core Affects Versions: 8.2.6.Final, 9.0.0.CR1 Reporter: Dan Berindei Assignee: William Burns Priority: Major Fix For: 9.4.2.Final After ISPN-6392, {{DistributedExecutorService.submit(...)}} nominally returns a {{CompletableFuture}}. However, it doesn't behave like a regular {{CompletableFuture}}, because it doesn't run the failure policy until the user calls {{future.get()}}. {{future.isComplete()}} will return {{true}} before running the failure policy, and {{future.whenComplete(callback)}} will also execute the callback before running the failure policy.
