The logging use of FileLock is a bit unusual but looking at it now then 
I don't see the reason why it needs to use CREATE_NEW. I don't think 
DELETE_ON_CLOSE is suitable here as that work is for transient work 
files which isn't the case here. Instead it could use deleteOnExit to 
have some chance of removing it on a graceful exit.

BTW: Do you know why locks is Map? Would a Set do?
