The behavior of methods
File javax.swing.filechooser.FileSystemView.createFileSystemRoot(File f)
and public boolean isFileSystemRoot(File dir) do not match each others.
Under Windows platform createFileSystemRoot method returns file
for which isFileSystemRoot returns false.

Here is minimized test:

import javax.swing.filechooser.*;
import java.io.*;

public class FileSystemViewTest02 {
    public static void main(String[] args) {
        MyFileSystemView fsv = new MyFileSystemView();
File file = new File("");
File f = fsv.createFileSystemRoot(file);
        System.out.println(f);
        System.out.println(fsv.isFileSystemRoot(f));
    }
}

class MyFileSystemView extends FileSystemView {

    public File createNewFolder (File f) throws IOException {
System.out.println("createNewFolder called");
return null;
    }

    public File createFileSystemRoot(File f) {
return super.createFileSystemRoot(f);
    }
}

--- Output ---

false
