Sijie Guo commented on BOOKKEEPER-604:
--------------------------------------
I don't think the fix is right. the case would not happen at that place that
the patch tried to fix, since it is protected under a synchronized block.
the race could only happen after it got the firstEntryList and started to flush
and deleteLedger kicked in. I think a simple fix is we should call getFileInfo
once and use this fileInfo acrossing the flush period and release it only after
flushing is done.
> Ledger storage can log an exception if GC happens concurrently.
