[classlib][luni] FileDescriptor.sync() throws unexpected SyncFailedException when the descriptor is read-only. 
---------------------------------------------------------------------------------------------------------------

                 Key: HARMONY-1494
                 URL: http://issues.apache.org/jira/browse/HARMONY-1494
             Project: Harmony
          Issue Type: Bug
          Components: Classlib
            Reporter: Andrew Zhang


Following test case reproduces the bug:
    public void testSyncReadOnly() throws Exception {
        String TESTFILE = "tempFile";
        try {
            FileOutputStream fos = new FileOutputStream(TESTFILE);
            fos.write("something".getBytes());
            fos.close();

            RandomAccessFile raf = new RandomAccessFile(TESTFILE, "rw");
            raf.getFD().sync();
            raf.close();

            FileInputStream fis = new FileInputStream(TESTFILE);
            fis.getFD().sync();
            fis.close();
        } finally {
            new File(TESTFILE).delete();
        }
    }
The test passes against RI while fails against Harmony. I'll try to fix this problem. 

Best regards,
Andrew
