Serializing InputStream as ByteArray using BeanProxy

[martypitt1]

[Note:  Also posted on StckOverflow here]

I'm trying to serialize an object which has an InputStream.  I need it to arrive on the flex client as a ByteArray.

Note - I can't implement `IExternalizable` on this class, as it's not mine.

I've registered a custom `BeanProxy` to do the conversion, however it doesn't appear to be working:

   public class InputStreamBeanProxy extends BeanProxy {
        @Override
        public Object getInstanceToSerialize(Object instance) {
       
            InputStream stream = (InputStream) instance;
            Byte[] boxOfBytes;
                try {
                    byte[] bytes = IOUtils.toByteArray(stream);
                    boxOfBytes = new Byte[bytes.length];
                    for (int i=0; i < bytes.length; i++)
                    {
                       boxOfBytes[i] = bytes[i];
                    }
                } catch (IOException e) {
                    logger.error("Exception serializing inputStream: ", e);
                    throw new RuntimeException(e);
                }
                return boxOfBytes;
           }
    }

This proxy is then registered during startup as follows:

    PropertyProxyRegistry.getRegistry().register(InputStream.class, new InputStreamBeanProxy());

I've set breakpoints in this code, and I see it being called as expected.  However when the object arrives on the client, the input stream is typed as `Object`, and it contains no properties.

What am I doing wrong?

Thanks,
