> 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.
