> {{BaseDistributionInterceptor.primaryReturnHandler()}} doesn't replicate writes to the backups if {{cacheConfiguration.clustering().hash().numOwners() == 1}}. That check is incorrect, because a segment can have more owners than configured:
> 1. In a replicated cache, the configured {{numOwners}} is ignored, and all the members are owners.
> 1. Even in a distributed cache, during rebalance, the segments being moved will have more than {{numOwners}} owners.
