[infinispan-issues] [JBoss JIRA] (ISPN-3103) StateRequestCommand requests serialization of type for which no Externalizer exists

StateRequestCommand requests serialization of type for which no Externalizer exists ----------------------------------------------------------------------------------- Key: ISPN-3103 URL: https://issues.jboss.org/browse/ISPN-3103 Project: Infinispan Issue Type: Enhancement Components: State transfer Reporter: Sanne Grinovero Assignee: Mircea Markus Priority: Critical Attachments: ISPN-3103_cow_externalized.patch RPC org.infinispan.statetransfer.StateRequestCommand sends a parameter defined as type Set (field segments) which is implemented by a java.util.concurrent.CopyOnWriteArraySet. This implementation is Serializable but seems to be quite slow as we don't have a custom Externalizer for it.
