Name: mlR10151 Date: 04/04/2001



The spec. for the MemoryCacheImageOutputStream.close() says nothing about throwing
IndexOutOfBoundsException, but it does throw it:

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

public class a {
    public static void main (String argv[]) throws Exception {
        OutputStream ostream = new ByteArrayOutputStream();
        MemoryCacheImageOutputStream mcios = new MemoryCacheImageOutputStream(ostream);
        mcios.close();
        System.out.println("Passed");
    }
}
