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

[Sanne Grinovero (JIRA)]

    [ https://issues.jboss.org/browse/ISPN-3103?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13020533#comment-13020533 ] 

Sanne Grinovero commented on ISPN-3103:
---------------------------------------

When fixing this, let's also keep in mind that serializing a structure which needs to be a concurrent collection is racy. Make sure the right version of the contents is sent across the wire!

> 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.
