Koloom commented on NET-146:
----------------------------
Following is an InputStream implementation which slows down the data transfer
(upload). Just to make your testing easier ;-). I could not attach the complete
test since I use another layer on top of commons-net and I am not free to
distribute it.
public class DelayedByteArrayInputStream extends InputStream {
private byte[] data;
private int position;
private long chunkDelay;
private final static int CHUNK = 10000;
public DelayedByteArrayInputStream(byte[] data, long time) {
this.data = data;
position = 0;
double x = time / (data.length / CHUNK);
chunkDelay = Math.round(Math.ceil(x));
}
public int read() throws IOException {
if (position % CHUNK == 0) {
try {
Thread.sleep(chunkDelay);
}
catch (InterruptedException e) {
throw new IOException("sleep
interrupted");
}
}
return position < data.length ? data[position++] : -1;
}
}

> Key: NET-146
> URL: http://issues.apache.org/jira/browse/NET-146
> Project: Commons Net
> Issue Type: Bug
> Affects Versions: 1.4 Final
> Environment: linux 2.6, java 1.5.0_08 (but most probably any
> environment)
> Reporter: Koloom
>
> If you set a timeout on the control connection and then make a data transfer
> (upload, download) which takes longer than that timeout, the client throws
> the following exception. It seems like the client tries to read something
> from the control connection while the data transfer is in progress and then
> it just throws an exception. It makes the application think that the transfer
> failed even though it succeeded.
