[infinispan-issues] [JBoss JIRA] (ISPN-4103) RHQ server plugin: generic loader cache child creation fails

[William Burns (JIRA)]

    [ https://issues.jboss.org/browse/ISPN-4103?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12953944#comment-12953944 ] 

William Burns commented on ISPN-4103:
-------------------------------------

This issue is actually slightly different than ISPN-4104, that one the store addition is actually working properly.  The problem with the case provided is it doesn't follow the requirements to locate the configuration builder.  This one however the loader class was never implemented, so just adding similar code should allow it to behave similarly.

> Creation of cache child -- cluster loader is ok. 
> However, when trying to create the same using generic loader child resource, it fails with following message [1].
> Server probably wasn't updated for latest persistence (loaders/stores) changes and only allows 5.2 based loaders/stores.
> Operation call from RHQ point of view looks to be clear and OK.
