ReplicationDB.java:
Collapsed try/finally embedded in try/catch into single try/catch/finally statements.
Used a static import for OperationStatus.SUCCESS to help readability with if statement conditions.
In count(), moved the cursor variable inside findFirstCounterRecordAfterStartPoint() and findFirstCounterRecordBeforeStopPoint() to ease readability.
In ReplServerDBCursor ctor, removed an uneeded else statement (because of an early exit)
