[jbosscache-issues] [JBoss JIRA] Commented: (JBCACHE-1602) NodeSPI.isDataLoaded is false for new node with optimistic locking

[Dennis Reed (JIRA)]

    [ https://issues.jboss.org/browse/JBCACHE-1602?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12615780#comment-12615780 ] 

Dennis Reed commented on JBCACHE-1602:
--------------------------------------

The cause is in LegacyCacheLoaderInterceptor#loadNode:

      if (n != null && !n.isDataLoaded())
      {  
         if (trace) log.trace("Setting dataLoaded to true");
         n.setDataLoaded(true);
      }

With MVCC or Pessimistic locking, this is executed.
With Optimistic locking, n is null, so this is skipped.

>     cache.put ( fqn, key, test );
