Description

When I try to upload a file to an FTP server via org.apache.commons.net.ftp.FTPClient.storeFile(String, ImputStream), everything seems to work well. The method returns true, the reply string seems to be OK, I also see in the FTP server that there was a successful transfer. However, zero bytes are transfered, although the ByteArrayInputStream used as the second argument has some data (some hundreds of bytes). When I capture the network traffic with Wireshark, I also see that everything seems to be OK, but the data connection actually transfers no data. Immediately after the TCP handshake, the client closes the connection with FIN. I tried to use a CopyStreamListener to see what's going on - it reports successful transfer of the expected number of bytes. When I perform the same test with Commons Net 2.2 instead of Commons Net 3.0, it works properly - my data gets uploaded, and I get the same OK responses as with 3.0. When switching between 2.2 and 3.0, I do not compile anything.
