[hibernate-dev] Configuration for Infinispan cache working as directory provider in HSearch

[Emmanuel Bernard]

How do you share the cache between different directories?
A static field would not work well as it would prevent HSearch to be  
started twice in a single app.

Anyway if we share the cache, I would still like to use the per  
directory provider configuration strategy (from a config property  
point of view) and raise an exception if it turns out the Infinispan  
cache config is different between two different indexes. That way we  
can improve down the road.
