In the java policy file what will happen if we comment out

//permission java.lang.RuntimePermission "stopThread";.


My understanding is that we can't call thread.stop() anywhere in the program am i rite?
If we call it should say "Access denied"... But we should be able to work on with thread.start and thread.run


If any Text area is built with AWT closing it by clicking on "X" on the window will call this thread.stop() method?

This permission only allows code to stop a thread if it has previously been granted permission to access that thread.
However, you shouldn't be calling the stop() method on a Thread anyway. The method was deprecated years ago because it is inherently unsafe and can cause bugs which are horribly difficult to trace. Consequently you should never grant this permission.

Closing an AWT window doesn't call stop() on any thread as far as I'm aware.
