> {{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.
