[jboss-jira] [JBoss JIRA] (AS7-3808) CacheLoaderException: Root not directory or IO error occurred

[Paul Ferraro (JIRA)]

    [ https://issues.jboss.org/browse/AS7-3808?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12671045#comment-12671045 ] 

Paul Ferraro commented on AS7-3808:
-----------------------------------

Well, as far as better wording, what's happening is File.listFiles(...) is returning null, which according to the spec indicates that either the File in question is not a directory (or doesn't exist at all) or there was an I/O issue, the details of which are not obtainable.  If we assume it wasn't an I/O issue, and we know that the File in question is most definitely a directory, that leaves only the possibility that it doesn't exist.

> While testing failover on undeploy, I ran into rather cryptic exception: 
> "Root not directory or IO error occurred"
> The machine shouldnt run into IO errors, probably related AS7-3161? Can we get a better wording here as well?
