Sebb commented on NET-447:
--------------------------
Have you tried with the current release, which is 3.1? Should be a drop-in
replacement for 2.0.
2.0 is very out of date.
> Commons-net version 2.0 jar unable to download files of time stamp 29th
> February.

> Key: NET-447
> URL: https://issues.apache.org/jira/browse/NET-447
> Project: Commons Net
> Issue Type: Bug
> Components: FTP
> Affects Versions: 2.0
> Environment: Windows Server 2003.
> Reporter: Jeevesh Mishra
> Labels: patch
> Fix For: 2.0
>
> Original Estimate: 1,304h
> Remaining Estimate: 1,304h
>
> When FTP Client of commons-net.jar (version 2.0) tries to get the list of
> files on FTP server then for the files of time stamp date 29th Feb 2012 it
> returns null value and in turn throws Null pointer Exception.
> Because the files are read in date viz sequence, thus it reads the file names
> correctly till 28th Feb but as soon as it gets a file of time-stamp date 29th
> it throws Null Pointer Exception and all the files after that are not read.
> Also its been mentioned in the case mentioned at following url that this
> issue has been resolved in version 1.5 :
> https://issues.apache.org/jira/browse/NET-188
> Thus ideally such solution would have been included in all later versions. We
> would require a patch to resolve this.
> Also for your information we are using Wicket frame work. Do you forsee any
> Jar conflict with commons-net version 2.0 in such scenario.
> We are also attaching the Exceptions trace as follows:
