Why not use the SafeOrderedExecutor as BookKeeper does?

bitwise &, I guess you meant && here.

I dont like boolean flags like readForward being passed to the constructor
here. I think it would be better to have a class called
SingleFragmentCallbackWithForwardRead which inherits from
SingleFragmentCallback. You can then overload processResult on that.

bq. Summary
bq. -------
bq.
bq. Bookie recovery updates the ledger metadata in zookeeper. LedgerHandle
will not get notified of this update, so it will try to write out its own
ledger metadata, only to fail with KeeperException.BadVersion. This effectively
fences all write operations on the LedgerHandle (close and addEntry). close
will fail for obvious reasons. addEntry will fail once it gets to the failed
bookie in the schedule, tries to write, fails, selects a new bookie and tries
to update ledger metadata.
bq.
bq. Update Line 605, testSyncBookieRecoveryToRandomBookiesCheckForDupes(),
when done
bq. Also, uncomment addEntry in
TestFencing#testFencingInteractionWithBookieRecovery()
