camel-ftp 2.10.4 fails to connect on windows

[xuloo <tr...@xuloo.cc>]

I'm building an Eclipse RCP application - i've created a plug-in which uses
Camel and, more specifically, the camel-ftp component to connect to an FTP
server.

FTP server is vsftpd running on a ubuntu 12.x box with standard config.

running the application from my macosx 10.8.2 machine it connects fine and
polls the server, pulls files... all is well.

However, when connecting from windows 7 (haven't tested other windows
versions) i get this:

20954 [Camel (camel-1) thread #0 - ftp://username@1.2.3.4] INFO

seems to be trying to do a windows-style backslash and fails (cause that
directory doesn't exist).

I've googled the hell out of this and can't find any hint of anyone else
having the same problem, nor can i find any suggestion for a camel-ftp
setting that would allow me to sidestep this.

Any suggestions?

Seems to be related to this:

http://serverfault.com/questions/262760/vsftp-path-with-backslash

Camel, on windows, is telling the ftp server to cd \.

on mac it does something different - i'm assuming it uses a forward slash /.

so a camel-ftp client running on windows (within eclipse RCP, at least)
can't connect to a FTP server running on a *nix system?

That doesn't sound right to me. Surely someone must have come across this
before?

I'll put up a windows server to test if it connects ok - but would like a
more suitable fix but i'm guessing there's a platform-specific
FILE_SEPARATOR that can't be overridden?
