Improve transactions performance by defining a non-system hashCode
------------------------------------------------------------------

                 Key: ISPN-1456
                 URL: https://issues.jboss.org/browse/ISPN-1456
             Project: Infinispan
          Issue Type: Enhancement
          Components: Transactions
            Reporter: Sanne Grinovero
            Assignee: Sanne Grinovero
             Fix For: 5.1.0.BETA2


I'm experiencing an impressively high overhead of Object.hashCode for org.infinispan.transaction.xa.TransactionXaAdapter, being invoked in the TransactionManager to store it HashTable(s). Adding a simple hashCode implementation provides a 5X performance improvement in synthetic microbenchmarks.
