It's because you are not running the program with stdout attached to a
terminal or terminal emulator. Probably, you are running in a console
window.

Cygwin can emulate a terminal in a console window for programs that do
all I/O through it, but for third-party applications, like Sun java, it
cannot.

Run the application in rxvt and it works as expected.
