[classlib][nio] java.nio.charset.CharsetEncoder.flush() throws unexpected IllegalArgumentException
--------------------------------------------------------------------------------------------------

                 Key: HARMONY-1849
                 URL: http://issues.apache.org/jira/browse/HARMONY-1849
             Project: Harmony
          Issue Type: Bug
          Components: Classlib
            Reporter: Svetlana Samoilenko
            Priority: Minor


Description:
Unexpected IllegalArgumentException: "The length must be positive" was thrown on closing OutputStreamWriter
object.
RI works fine without any exceptions.

import junit.framework.TestCase;
import java.io.*;
   public class test extends TestCase{    
       public void testclose() throws IOException { 
           OutputStreamWriter osw = new OutputStreamWriter(new FileOutputStream("file"));
                  
           try {
                // write a surrogate pair char, then, write a char 0x0001 in order
                // to create a malformed surrogate element, expect nothing since specification
                // says the behavior is unspecified.
               osw.write(0xD800); 
               osw.write(1);
            } catch (Throwable e) {
                //expected
            } finally {                
                 osw.close();
            }        
    }
}
