Anthony Maire commented on LOG4J2-1397:
---------------------------------------
At first sight, this approach may work correctly in a single-threaded context,
but I think you need 1 more preallocated buffer than the ringbuffer size (so
need to use a modulo instead of a binary mask).
However in our application, this code can be invoked by several threads.
Since the order in which buffers are obtained from the pre-allocated pool might
not be the same as the order they are in the ringbuffer, the application will
then need a callback to know that a buffer has been released (i.e logged to
disk).
