Abstract: In accordance with an embodiment, described herein is a system and method for handling lazy deserialization exceptions in an application server environment. When a stateful, e.g., EJB client request arrives to the EJB container, if the container detects that it cannot deserialize the state on this server and a patching (Patching, Zero Downtime Patching, ZDT) application upgrade rollout is in progress, the container can ask the replication manager to replicate the bean state to a new secondary that is in the opposite ZDT failover server group of this server, if it can find one. A remote reference of the replica on the new secondary will be set to a special type exception, which carries the replica's remote reference to the client side, in order to fulfill the client request.
