[jbosscache-issues] [JBoss JIRA] Commented: (JBCACHE-1441) DataContainerImpl.toString() can throw UnsupportedOperationException

[Manik Surtani (JIRA)]

    [ https://jira.jboss.org/jira/browse/JBCACHE-1441?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12437337#action_12437337 ] 

Manik Surtani commented on JBCACHE-1441:
----------------------------------------

I don't understand how you could have recreated this with a standard setup.  DataContainerImpl.numNodes() is *only* called if you ate *not* using MVCC, but looking at your stack you are using MVCC ("at org.jboss.cache.mvcc.NodeReference.getChildrenDirect(NodeReference.java:267) ").

This cannot happen in normal usage, so what was your EasyMock setup doing?  Perhaps you didn't set DataContainerImpl.usingMvcc properly?
