[jira] [Created] (SOLR-9453) NullPointerException on PeerSync recovery

Michael Braun created SOLR-9453:
-----------------------------------

             Summary: NullPointerException on PeerSync recovery
                 Key: SOLR-9453
                 URL: https://issues.apache.org/jira/browse/SOLR-9453
             Project: Solr
          Issue Type: Bug
      Security Level: Public (Default Security Level. Issues are Public)
    Affects Versions: 6.2
            Reporter: Michael Braun


Just updated to 6.2.0 (previously using 6.1.0) and we restarted the cluster a few times - for one replica trying to sync on a shard, we got this on a bootup and it's seemingly stuck. Cluster has 96 shards, 2 replicas per shard.
