Matteo Merli commented on BOOKKEEPER-841:
-----------------------------------------
[~hustlmsp] Very good point, I've changed the code to encapsulate the ledgers
map into an entry for ledgerId=-1.
There's still a unit test which I didn't catch before because I already had a
fix for BOOKKEEPER-695. I think that jira should be a pre-requisite to this
patch, given that instead of scanning, now the method returns directly the
EntryLogMetadata, so in case of exceptions there will be no partial result
available.
