'Exiting' (ctrl+c) a process from console - Eclipse vs Intellij

It seems that in Eclipse, if you want to send ctrl+c to a process you cant. The terminate button on the console just kills the running process without running the shutdown hooks. I know that java itself doesnt allow sending a signal to another process.

However it seems that intellij idea does have a 'exit' button next to its 'stop' button which does allow shutdown hooks to run.

Can somebody tell me how intellij does this?

I need to send ctrl+c from my program to another java process too.

Intellij use a native library to send a signal on Windows and the command kill on Unix.
Here is a source code

Has you said you can't send a signal in Java. So you need to execute native code.

It is my understanding that this happens only on Windows with Eclipse. Also see: https://bugs.eclipse.org/bugs/show_bug.cgi?id=38016

As far as just testing your hooks you can do it by calling System.exit() and then I suppose your users will not run the application using Eclipse so it's ok to count on it working for them.
