Uwe Schindler commented on LUCENE-6507:
---------------------------------------
The naming of this method was always trappy. I did not touch that last year
when I refactored the lock factories.
The method is just a factory to create an instance of the Lock class. Maybe it
should be called "newLockInstance", then it would be clear what happens.

>
> the lock API in Lucene is super trappy since the lock that we return form
> this API must first be obtained and if we can't obtain it the lock should not
> be closed since we might ie. close the underlying channel in the NativeLock
> case which releases all lock for this file on some operating systems. I think
> the makeLock method should try to obtain and only return a lock if we
> successfully obtained it. Not sure if it's possible everywhere but we should
> at least make the documentation clear here.
