Message transformation gets empty content (only) for large messages

[Nicklas Karlsson]

Hi,

I'm trying to do message tranformations based on examples from Stack
Overflow etc and I have something on 3.0.4 like

public MessageXMLDecodeOutInterceptor() {
   super(Phase.PRE_STREAM);
}

public void handleMessage(Message message) {
   try (OutputStream outStream = message.getContent(OutputStream.class);
CachedOutputStream cachedStream = new CachedOutputStream();) {
      message.setContent(OutputStream.class, cachedStream);
      message.put(Message.ENCODING, charset.name());
      message.getInterceptorChain().doIntercept(message);
      cachedStream.flush();
      String origMessage = IOUtils.toString(cachedStream.getInputStream(),
charset);
      String newMessage = // modify the message
      IOUtils.write(header, outStream, charset);
      IOUtils.write(newMessage, outStream, charset);
   } catch (IOException e) {
      logger.errorf("Could not transform message", e);
   }
}

and it works until the message i large (~200k?), then suddenly the
origMessage is "". Are large messages somehow cached/handled differently?

Thanks in advance,
  Nik
