java.io.OutputStreamWriter.write(int) writes bytes in UTF-8 incorrectly
-----------------------------------------------------------------------

                 Key: HARMONY-2439
                 URL: http://issues.apache.org/jira/browse/HARMONY-2439
             Project: Harmony
          Issue Type: Bug
          Components: Classlib
            Reporter: Anton Ivanov


java.io.OutputStreamWriter works wrong when calling to its write(int) method if encoding specified
is UTF-8.
Following test fails:

import java.io.*;

public class TestOutputStreamWriterUTF8 {

  public static void main(String argv[]) throws Exception {
      ByteArrayOutputStream out;
      OutputStreamWriter writer = null;
      InputStreamReader isr = null;

      try {
          out = new ByteArrayOutputStream();
          writer = new OutputStreamWriter(out, "UTF-8");
          int upper = 9000;

          for (int c = 0; c < upper; ++c) {
              writer.write(c);
          }

          writer.flush();
          byte[] result = out.toByteArray();

          isr = new InputStreamReader(new ByteArrayInputStream(result),"UTF-8");

          int expected = 0;
          for (; expected < upper; ++expected) {
              if (expected != isr.read()) {
                  System.out.println("test FAILED:" + expected +" "+ isr.read());
                  break;
              }
          }
      
          if (expected == upper) {
              System.out.println("test PASSED");
          }

          isr.close();
          writer.close();
       } catch (Exception e) {
          e.printStackTrace();
       }
 }
}
