eclipse giving error when test program exits

I upgraded my Eclipse IDE version Kepler by downloading the new version (Luna) and replacing the old C:\Program FIles\Eclipse with the new (since there's no installer).

Now when I run a test program which displays a spinner, it runs fine until I close the window to exit the program. Then Eclipse Console Window displays:

Traceback (most recent call last):
  File "C:\Python27_x64\lib\site-packages\py2exe\boot_common.py", line 92, in <module>
ImportError: No module named linecache
Traceback (most recent call last):
  File "boot_com_servers.py", line 4, in <module>
ImportError: No module named win32api

I have no C:\Python27_x64... folder, I have no file named boot_common.py anywhere on my hard drive, nor do I have a file named boot_com_servers.py anywhere on my hard drive. I'm not sure why my Eclipse IDE is trying to run some Python code when I close the test program.

Here's my test code:

import javax.swing.JFrame;
import javax.swing.JPanel;
import javax.swing.JSpinner;


public class Test2 extends JPanel {

	  public static void main(String[] args) {
			JFrame frame = new JFrame();
			frame.setTitle("Test Spinner");
			frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
			frame.setSize(230, 90);
			frame.add(new JSpinner());
			frame.setVisible(true);
	  }
}

Select allOpen in new window

What's this error message all about?
