[infinispan-dev] Hybrid locking scheme in ISPN 5.2.0

[Diego Didona]

Thanks Galder,
   I am reading again the documentation you linked and I am also running 
some simple tests but I see this behaviour:
-  with OPTIMISTIC mode the lock is acquired *only* at prepare time 
(thus *not* like in ISPN 5.0);
-  with PESSIMISTIC mode the lock is acquired at encounter time on the 
primary node (again, thus *not* like in ISPN 5.0).

The behaviour I'm looking for is        only-local encounter-time 
locking + cluster-wide prepare-time locking.

Am I missing something?
Thanks again. Regards,
    Diego
