            }

    </fx:Script>
</s:WindowedApplication>

it's working great,but problem occurred when i restart my application without closing/killing java process from task manager.it's execution goes in NativeProcessExitEvent_handler box with process exit code 0.

i would like to know why it is happening and How to get rid of it?

please help me in this.
