Method write(int) of the FileImageOutputStream class falls into an infinite loop.
To reproduce the bug run the following test:

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

public class a {
    public static void main (String argv[]) throws Exception {
        System.setSecurityManager(null);
        File tempFile = File.createTempFile("test", "tmp");

        FileImageOutputStream fios = new FileImageOutputStream(tempFile);
        fios.writeBits(0xFFFFFFFFFFFFFFFFL, 0);
        fios.write(1);
        fios.seek(0);
        fios.writeBits(0xFFFFFFFFFFFFFFFFL, 1);
        fios.write(1);

        System.out.println("Passed");
    }
}
