[Galder Zamarreño (JIRA)]

    [ https://issues.jboss.org/browse/ISPN-986?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12593234#comment-12593234 ] 

Galder Zamarreño commented on ISPN-986:
---------------------------------------

Actually, it's not possible to have an annotation on the Externalizer itself, cos the framework will receive the object to be externalize, so how's it gonna figure out which, if any externalizers to use dynamically without any other hint? The annotation needs to be part of the class being externalized. This brings the following limitation:

- JBMAR Externalizer cannot be used with objects that cannot be modified by the user. To deal with such situations, the more advanced Infinispan Inner Externalizer method needs to be used where the externalizers are pre-registered.

> Look into how JBMAR sends Externalizers can be sent via the wire so that receiving side does not need to know about Externalizers in advance.
