[infinispan-issues] [JBoss JIRA] (ISPN-2232) Cache::re-start doesn't setup CommandInitializer in ComponentRegistry when used with Query

[Galder Zamarreño (JIRA)]

    [ https://issues.jboss.org/browse/ISPN-2232?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12714851#comment-12714851 ] 

Galder Zamarreño commented on ISPN-2232:
----------------------------------------

I can't replicate this latest issue. When the cache is restarted, the dependencies are rewired, including the QueryInterceptor.

Can you provide a test case to replicate this?
