Initially the synopsis was "JFileChooser's COM thread doesn't stop if a security manager installed", I changed it to reflect the actual issue better.

Run a simple test:
import javax.swing.filechooser.FileSystemView;

public class bug6570445 {
    public static void main(String[] args) throws Exception {
        System.setSecurityManager(new SecurityManager());
	// The next line of code forces FileSystemView to request data from Win32ShellFolder2,
	// what causes an exception if a security manager installed

The test throws an exception:

EVALUATION In Win32ShellFolder2, the shutdown hook's code should be surrounded with a doPrivilege block.
