I'm afraid that won't help with this issue. All a terminal does when
Ctrl+C is pressed is write a ^C character to its pseudo terminal
device (pty), and it's the pty driver that handles it (depending on
the pty's settings): Cygwin processes are sent a SIGINT signal, but
Windows processes such as Java are terminated outright.
