[Hibernate] DistributedCacheConcurrencyStrategy implemented !

[Christian M. <vc...@cl...>]

Hi all, got a little time today to investigate Gavin proposition about 
the DistributedCacheConcurrencyStrategy.
Here is a first shoot, it's based on javagroups to manage a distributed 
lock server ( block provided by javagroup ;) )

Since the lock server is distributed, even if one or more server in the 
cluster fail, the rest can still use the cache.

I used the latest javagroups version available with log4j 
(JavaGroups-2.0.3.log4j.bin.zip).
Few little things need to be done like using the mutators to set the 
multicast adr / port.

Give it a try , it's fun ;)
