Jono Morris commented on ZOOKEEPER-3735:
----------------------------------------
On the Master branch the FileSnap snapshot deserialize method has an 'if' block
that calls 'deserializeZxidDigest' on the data-tree, which sets
'*digestFromLoadedSnapshot*' on the data-tree to 'null' if the start zxid is
larger than the digest zxid in the snapshot (FileSnap ~ line 98; See the code
block in my previous comment).
Further down in FileSnap deserialize, the 'if' block skips the
'compareShapshotDigest' method (where the rate-logger call is made) when
'*digestFromLoadedSnapshot*' is null (FileSnap ~ line 116).
