The description for the FileCacheImageOutputStream.close()
says nothing about EOFException, but it does throw EOFEx if
seeked beyond the end of stream previously.

Note, RandomAccessFile does not throw any exception in such a case.

To reproduce the bug run the following test:
===================== a.java =======================
import javax.imageio.stream.*;
import java.io.*;

public class a {
    public static void main(String[] args) throws Exception {
        RandomAccessFile raf = new RandomAccessFile(new File("a.java"), "r");
        raf.seek(20000);
        raf.close();

        OutputStream ostream = new ByteArrayOutputStream();
        FileCacheImageOutputStream fcios = new FileCacheImageOutputStream(ostream, null);
        fcios.seek(20);
        fcios.close();
    }
}
===================== log =======================
