      Method writeBits(long,int) of the FileImageOutputStream class throws unexpected IOException.
      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, 1);
              System.out.println("Passed");
          }
      }
