[infinispan-issues] [JBoss JIRA] (ISPN-7889) BaseDistributionInterceptor.remoteGet may cause concurrency issues

BaseDistributionInterceptor.remoteGet may cause concurrency issues ------------------------------------------------------------------ Key: ISPN-7889 URL: https://issues.jboss.org/browse/ISPN-7889 Project: Infinispan Issue Type: Bug Components: Core Affects Versions: 9.1.0.Alpha1 Reporter: Radim Vansa Assignee: Dan Berindei Priority: Major {{BaseDistributionInterceptor.remoteGet}} or any call that accesses the context in an async future handler that is called multiple times in parallel may lead to concurrent modifications of the context. These calls are usually handled using {{CompletableFuture.allOf()}} or using a CF with counter, but if one of the calls results in exceptional completion of the composed future, the processing continues (e.g. with a retry). The other parallel operation handlers are not stopped, though. {{BaseDistributionInterceptor.remoteGet}} shouldn't be called in parallel because it does not even synchronize regular successful invocations. A problem like this caused failures in {{GetAllCommandStressTest}}, and the issue was addressed for {{GetAllCommand}} in ISPN-7884.
