The description for the FileCacheImageOutputStream.flushBefore(long pos)
says:

. . .
Throws:
            IndexOutOfBoundsException - if pos lies in the flushed portion of the stream.
. . .

But it goes without any exception:
===================== a.java =======================
import java.io.*;
import javax.imageio.stream.FileCacheImageOutputStream;

public class a {
    public static void main (String argv[]) throws Exception {
        OutputStream ostream = new ByteArrayOutputStream();
        FileCacheImageOutputStream fcios = new FileCacheImageOutputStream(ostream, null);
        try {
            fcios.write(new byte[10], 0, 10);
            fcios.flushBefore(5);
            fcios.flushBefore(4);
            System.out.println("Failed");
        } catch (IndexOutOfBoundsException e) {
            System.out.println("Passed");
        }
    }
}
