Pushkar Raste commented on SOLR-9310:
-------------------------------------

Since any race condition would be handled by limiting fingerprint upto the 
maxVersion will get in `getUpdates`, I could not think of compelling reason to 
uset in `getVersions()`. 

 It probably won't hurt to use `maxVersion` before returning versions

> I found that Peer Sync fails if a node restarts and documents were indexed 
> while node was down. IndexFingerPrint check fails after recovering node 
> applies updates. 
> This happens only when node restarts and not if node just misses updates due 
> reason other than it being down.
> Please check attached patch for the test.
