ChannelFutureProgressListener interface not working as expected!

["이희승 (Trustin Lee)"]

Hello Fahad,

It works for me on my Fedora 13 Linux.  What is your environment?  On
Windows, it may not work, but I don't remember exactly.  Zero copy file
transfer in Windows is broken anyway - please check out the FileRegion
API documentation.

HTH,
Trustin
