> In TX mode with write skew check on, ST executing puts may trigger a remote get.
> The condition in TxDistributionInterceptor.handleTxWriteCommand should probably be switched from
> {code}
> if (ctx.isOriginLocal() && !skipRemoteGet || command.isConditional() || shouldFetchRemoteValuesForWriteSkewCheck(ctx, command))
>      remoteGetBeforeWrite(ctx, command, recipientGenerator);
> {code}
> to 
> {code}
> if (!skipRemoteGet && (ctx.isOriginLocal() || command.isConditional() || shouldFetchRemoteValuesForWriteSkewCheck(ctx, command)))
>      remoteGetBeforeWrite(ctx, command, recipientGenerator);
> {code}
> EDIT:
> I have also registered a situation where the Prepare/Commit command was executed remotely from within the ST because the topology has changed during the remote get. This should be avoided as well.
