[infinispan-issues] [JBoss JIRA] (ISPN-1041) Ensure Callable isolation for distributed executors

Ensure Callable isolation for distributed executors --------------------------------------------------- Key: ISPN-1041 URL: https://issues.jboss.org/browse/ISPN-1041 Project: Infinispan Issue Type: Bug Components: Distributed Execution and Map/Reduce Affects Versions: 5.0.0.BETA1 Reporter: Vladimir Blagojevic Assignee: Vladimir Blagojevic Fix For: 5.0.0.BETA2 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.
