The spec for the "public FileImageInputStream(RandomAccessFile raf)" reads:

Throws:
 . . .
            SecurityException - if a security manager exists and does not allow read access to the file.

But it does not throw SecurityException:

========================== a.java =============================
import java.io.*;
import java.security.*;
import javax.imageio.stream.*;

public class a {
    public static void main (String argv[]) throws Exception {
        System.setSecurityManager(null);
        RandomAccessFile raf = new RandomAccessFile("a.java", "r");
        System.setSecurityManager(new mySecMgr());

        try {
            new FileImageInputStream(raf);
            System.out.println("Failed");
        } catch (SecurityException e) {
            System.out.println("Passed");
        }
    }
}

class mySecMgr extends SecurityManager {
    public mySecMgr() {}
    public void checkRead(String file) { throw new SecurityException(); }
    public void checkRead(FileDescriptor fdObj) { throw new SecurityException(); }
    public void checkRead(String file, Object context) { throw new SecurityException(); }
    public void checkPermission(Permission perm) { throw new SecurityException(); }
    public void checkPermission(Permission perm, Object context) { throw new SecurityException(); }
}
