[jira] Closed: (NET-247) NullPointerException after connect() in
FTPClient
Posted by "oliver zemann (JIRA)" <ji...@apache.org>.
[ https://issues.apache.org/jira/browse/NET-247?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
oliver zemann closed NET-247.
-----------------------------
Resolution: Invalid
I just noticed that it works when i use FTPClient instead of FtpClient - FtpClient is my own class - which does actually nothing:
public class FtpClient extends FTPClient
{
}
i will look at it whats wrong there.
sorry for disturbing
