Review Comment:
   Wondering if this would be an alternative:
   
   ```
   if (core != null) {
     ...
   }
   ```
   
   i.e. no `return;` statement and then the 
`replicationHandler.indexCommitPoint = commitPoint;` assignment could amount to 
`replicationHandler.indexCommitPoint = null;` which depending on the prior 
value is not the same as not assigning because of the `return`.
   
   Or if there's a `return` then could `IndexCommit commitPoint;` scope move 
into the `try` block?
