After updating to the latest cygwin, my Java processes no longer receive SIGINT signals. I have attached a simple Java program that adds a ShutdownHook that will print out when the correct signal is received and the main program sleeps indefinitely waiting for the signal.
I used to be able interrupt the process with Ctrl+C and with kill -2 <pid>. Neither of those methods work for me now.
Here is the version of Java that I am using:
java version "1.6.0_31"
Java(TM) SE Runtime Environment (build 1.6.0_31-b05)
Java HotSpot(TM) Client VM (build 20.6-b01, mixed mode)
Thanks,
Franz Kettwig

I can attest that Franz is not the only one with this problem. I just upgraded to Cygwin 1.7.15-1
but in vain. Is a fix in the works?

Not from me. I don't do Java.

python has the same problem. If you send it a Ctrl-C under cmd.com it
will print "KeyboardInterrupt" whereas under Cygwin it prints nothing.
Is python more to your taste?

Presumably you are referring to a native windows version of python, since:
d:\cyginst>bash
bash-4.1$ python
Python 2.6.7 (r267:88850, Feb 2 2012, 23:50:20)
[GCC 4.5.3] on cygwin
Type "help", "copyright", "credits" or "license" for more information.
>>> >Hit CTRL-C here<
KeyboardInterrupt
I know this is an astonishing, maybe even revolutionary idea, but maybe
somebody who wants to use these native windows applications under Cygwin
might want to step up to debug this type of thing.

I'm not offering to do that but will venture to guess that the text
back to the terminal is perhaps causing a block on the pipe leaving a
hung process.

There's no pipe when you're running in "cmd.com", as was reported for
python.

I thought the conversation stemmed from inter-process communication of
a signal between Cygwin runtime and native runtime applications.

Since apparently nobody wants to take ownership of this regression
I'll point out the workaround, for the benefit of those googling
and landing on this thread: start Java with -Xrs and use Ctrl-Break
instead of Ctrl-C. This will disable thread dump and break any
application that relies on normal signal handling, though.

For me the following solution worked:
http://stackoverflow.com/questions/8014916/control-break-not-working-in-java-using-cygwin
Add global env variable 'CYGWIN' and set the value to 'tty'.
Now CTRL+C works for me.

You're using an old version of Cygwin. The CYGWIN=(no)tty option
has been removed a while ago:

To help debugging this (for whoever may start an effort, including
myself eventually), some more diagnostics:
Let's clearly distinguish 2 things:
- Interrupt the JVM with Ctrl-C (or kill -2): this works perfectly. It
didn't work though in some snapshots between 1.7.17 and 1.7.18, see
http://cygwin.com/ml/cygwin/2013-01/msg00196.html
- Invoke the JVM interrupt hook: this does not work in mintty but it
does in cygwin console.
However, it can be forced *not* to work in cygwin console either by
redirecting *both* stdin and stdout:
cat | java ... | tee /dev/null
