[jboss-jira] [JBoss JIRA] Commented: (JBESB-303) exception in helloworld_ftp_action

[Bruno Georges (JIRA)]

    [ http://jira.jboss.com/jira/browse/JBESB-303?page=comments#action_12349552 ] 
            
Bruno Georges commented on JBESB-303:
-------------------------------------

This error doesn't have to throw an exception. 
It is normal behavior to have an NLST [name list of remote directory] command which returns an empty file list.
For debugging purpose, this will be logged at debug level.
