------------------------------------
Thanks for the patch, good catch! I applied it at
http://svn.apache.org/viewvc?rev=1755514&view=rev
Re. the integration test: I'm a bit concerned about the dependency on timing.
These are the kind of tests prone to failure on CIs. Could it be done without
depending on timings? I.e. disable the flush thread and invoke flush manually a
couple of times?

> TarMK flush thread should run every 5 secs and flush the current root head to
> journal.log. It would be good to have a metric to capture the number of runs
> per minute
> This would help in confirming if flush is working at expected frequency or
> delay in acquiring locks is causing some delays
