[GitHub] [kafka] apovzner commented on pull request #5557: KAFKA-7128: Follower has to catch up to offset within current leader epoch to join ISR

[GitHub]

I moved this up because it seems safer. The code above also calls 
`getOrCreateReplica` for all replicas in ISR. I am not sure if we can get 
LeaderAndIsr for new partition where there are no replicas in ISR (in 
leaderAndIsr request) -- probably not? So, probably there is no bug in the 
original code, but still seems safer to call `createOrGetReplica` earlier, 
before trying to use any Replica object.
