How is this related to JBoss Cache?
Certain design ideas and indeed some code has been borrowed from JBoss Cache 3.x, however JBoss Cache is in no way a dependency. Infinispan is a complete, separate and standalone project. Some may consider this a fork, but the people behind Infinispan and JBoss Cache see it as an evolution, since all future effort will be on Infinispan and not JBoss Cache.
