Ensure Callable isolation as it gets invoked across the cluster
---------------------------------------------------------------

                 Key: ISPN-1041
                 URL: https://issues.jboss.org/browse/ISPN-1041
             Project: Infinispan
          Issue Type: Bug
          Components: Distributed Cache
    Affects Versions: 5.0.0.BETA1
            Reporter: Vladimir Blagojevic
            Assignee: Vladimir Blagojevic
             Fix For: 5.0.0.CR1


If Callable submitted for distributed execution contains mutable instance fields they might get mutated locally before being sent for a remote execution thus potentially resulting in wrong results being returned to a task invoker. Just before Callable is dispersed across cluster it gets invoked locally where instance fields of a submitted Callable can be possibly mutated; Callable is in turn sent to remote nodes with mutated values instead of "original" field values as submitted by user. 

We need to ensure that each execution node gets a pristine version of Callable object submitted by the user.
