FTP upload stops when uploading to IIS FTP service "550 "

Hi

when uploading to a Microsoft IIS FTP server there are some cases, when IIS FTP server does not conform strictly to RFC 959. For example when uploading to a non-existing subfolder Microsoft IIS responds with "550 ", giving the return code but omitting the reason.

This throws a MalformedServerReplyException in Netbeans. (Please see the complete error log underneath).

I believe, that this behaviour can be optimized by using the function https://commons.apache.org/proper/commons-net/apidocs/org/apache/commons/net/ftp/FTP.html#setStrictReplyParsing(boolean) .

I understand, that this is strictly a Microsoft bug, but hopefully this can be updated in Netbeans since I do not see any chance of Microsoft changing this bug any time soon.

I would really apreciate it, if this can be "fixed" in the next version.

Thanks and Greetings from Germany
