@sijie I am going to use this improvement in order to make a necessary
change in order to support java9. I would like to make 4.5 runnable on java9 as
we are starting to test all of our apps and bookies cannot run on java9 without
hacks
> use native fallocate & sync_file_range to improve journal allocation
