Hi Andy
Thanks for the complete test case, which is very useful. Just a couple of
things:
I see that in your tests, you have the following:
{code:java}
if (files.length==0)
{
LOG.info("No files? BROKEN!!!!!!!!!!!!!");
throw new IOException("broken");
}
{code}
But a zero-length array is a valid return value if a directory is empty.
Also, could you by any chance run this in debug mode and break execution when
the program locks up? What would be very useful is a stack trace in this
situation.

> Key: NET-315
> URL: https://issues.apache.org/jira/browse/NET-315
> Project: Commons Net
> Issue Type: Bug
> Affects Versions: 2.1
> Environment: Ubuntu x86_64 9.04, Java x86_64 1.6.0_16-b01
> Reporter: Andy Brook
> Attachments: commons-net-problem.zip

>
> I have several servers that I'm spidering with FTPClient, I initially thought
> there was something wrong with what Im doing, however, dropping the version
> back to 2.0, and what I'm seeing goes away.
> the following 'System Names' exhibit this lockup behaviour:
> ||System || Works|| Notes ||
> |UNIX Type\: L8| (x)| several sites Im talking to respond with this |
> |System Name\: null | (x) | I found that on connect its telling me
> "Windows_NT"|
> Ubuntu 6.06 and 9.04 systems work fine.
> Attached will be a test-case maven project, just edit the 'blank.properties'
> in resources, with valid ftp server values. With commons-net-2.1 it locks
> up, but backing off to 2.0, it works.
