[infinispan-dev] BoundedConcurrentHashMap

[Vladimir Blagojevic]

Hey Sanne,

I implemented first versions of LIRS as Manik challenged me to implement it
:-) This was back in early 2010. Then Will took over, simplified it and
fixed some subtle bugs. Finally, Ban Manes took the whole thing over to
Caffeine.

Cheers,
Vladimir
