> When we were adding bi-directional sync support in CDCR ( SOLR-11003 ) we 
> changed the CDCR Update Log codec to write an extra bits. 
> When we use the RealTimeGet component on a cluster running CDCR and have 
> in-place updates in the update log we will falsely trip an assert thus 
> causing the request to fail
> Here's the proposed change
> {code:java}
> -                 assert entry.size() == 5;
> +                 if (ulog instanceof CdcrUpdateLog) {
> +                   assert entry.size() == 6;
> +                 }
> +                 else {
> +                   assert entry.size() == 5;
> +                 }{code}
