b20.1 handled it differently.  If I press the [X] or
CTRL-BREAK in a b20.1 window, JDK dutifully dumps the
stack trace.

Just one of several things that worked in b20.1 that are
broken in cygwin 1.x.

Cygwin has considered CTRL-BREAK to be the same thing as CTRL-C for
about five years or so.

The fact that this inconveniences JDK is regrettable but I'm not going
to change well established behavior just to accomodate some non-cygwin
program.
