   …lementation.
   
   This bug was exposed by the test from HBASE-25924 and is only applicable for
   Async FSWAL implementation. Since this wal implementation closes the wal
   asynchronously, replication can potentially miss the trailer bytes.
   (see jira comment for detailed analysis).
   
   While this is not a correctness problem (since trailer does not have any 
entry data),
   it erroneously bumps a metric that is used to track skipped bytes in WAL 
resulting
   in false alarms which is something we should avoid.
