> Hi,
> We experience occasional encoding errors where a small number of two-byte
> chars get encoded wrong in an otherwise correct encoded message. I have
> traced the problem to the writeCacheTo method of CachedOutputStream where the
> temp cached file is read as 1024 bytes at the time which are then converted
> to a String before getting appended to the StringBuilder. If the 1024 byte
> boundary falls right between the two bytes of a two byte char the encoding
> fails.
> public void writeCacheTo(StringBuilder out, String charsetName) throws
> IOException {
> flush();
> if (inmem) {
> if (currentStream instanceof ByteArrayOutputStream) {
> byte[] bytes = ((ByteArrayOutputStream)currentStream).toByteArray();
> out.append(IOUtils.newStringFromBytes(bytes, charsetName));
> } else {
> throw new IOException("Unknown format of currentStream");
> }
> } else {
> // read the file
> FileInputStream fin = new FileInputStream(tempFile);
> byte bytes[] = new byte[1024];
> int x = fin.read(bytes);
> while (x != -1) {
> out.append(IOUtils.newStringFromBytes(bytes, charsetName, 0, x));
> x = fin.read(bytes);
> }
> fin.close();
> }
> }
> Below is a couple of lines from the hex-dump of the cache-file where you can
> see that the second o-slash in the file fall on a 1024 byte boundary and
> therefore gets corrupted in the outgoing message:
