“…As replication is transparent to programmers, our exception handling system can easily be compared with other existing EHSs. Various proposals address the issues related to exception handling for active objects integrating asynchronous communication [2,10,3,8,13,14,15,1]. Our solution is original in that it combines the following features: handling of request / response interactions between agents, handling of agent replicas, encapsulation and reactivity, ability to write context-dependent dynamic scope handlers (callercontextualization), ability to coordinate and control groups of active agents collaborating to a common task, ability to configure the exception propagation policy by defining exception resolution functions at the service level.…”
