RE: [net] Strange System.out behavior

[Julius Davies <ju...@cucbc.com>]

Hi, Chris,

To me that sounds like the sort of thing that might happen if:

- You changed JDK?
- You changed Operating System?
- You are using a different console/terminal?

I don't think it would have anything to do with Commons-Net, but I wouldn't want to stake my life on that either.  ;-)

So if you do this, you see nothing?

=================
System.out.print("Uploading file: " + convertSlashes(next) + "...");
System.out.flush();
=================

yours,

Julius

Subject:	Strange System.out behavior
Hi all --

   I just ported over my previous application to the Commons/Net FTP
library, and I'm seeing a strange bug.  The following snippet used to work:

	System.out.print("Uploading file: " + convertSlashes(next) + "...");
	InputStream in = new FileInputStream(f);
	ftp.storeFile(convertSlashes(next), in);
	System.out.println("done");

    But now nothing gets printed until the println.  I even tried adding a
System.out.flush(), but no dice.  Nothing's printed to the console without a
println().
    Any ideas what's going on?

   Nope.  Same JDK, same OS, same console.  As it turns out, it works when I
run as a standalone program -- the bug appears to be in the way Ant handles
System.out, although I would almost swear Ant was handling this fine before.

   Right.  Ant apparently embargoes all the output to System.out until a
newline is reached, which probably isn't intended behavior, exactly, but
what can you do?
