In non-tx cache, when conditional command (e.g. ReplaceCommand) fails on primary owner because the old value is not equal to current value, the NonTxDistributionInterceptor.visitReplaceCommand returns false but the entry is committed in EntryWrappingInterceptor anyway.

Speaking about EntryWrappingInterceptor.invokeNextAndApplyChanges: NonTxDistributionInterceptor does not mark the command as unsuccessful if it fails on the primary owner, therefore, checking for command.isSuccessful() in order to retry the command upon topology change may seem insufficient.
