NullPointerException on java server side when Flex client calls consumer.subscribe()

[Maxim Kopeyka]

Hi Guys,

I have this error with Flex client only, java client works fine...

granite-client-flex-3.2.0-SNAPSHOT.swc has been used to compile Flex client

Server side

=========

    public Heartbeat() {

        super();

        ChannelFactory channelFactory = new AMFChannelFactory();

        channelFactory.start();

        MessagingChannel channel = null;

        try {

            channel = channelFactory.newMessagingChannel(ChannelType.LONG_POLLING, "longPollingChannel", new URI("http://172.26.27.94:8084/gravityamf/amf"));

        } catch (URISyntaxException e) {

            LL.error(e.getMessage(), e);

        }

        producer = new Producer(channel, "my-destination", "my-heartbeat");

    }

    @Scheduled(fixedRate = 2000)

    public void heartbeat() {

        try{

            AsyncMessage msg = new AsyncMessage();

            msg.setTimeToLive(TTL);

            msg.setTimestamp(System.currentTimeMillis());

            msg.setClientId(UUID.randomUUID().toString());

            msg.setMessageId(UUID.randomUUID().toString());

            msg.setBody("my-heartbeat");

            msg.setDestination("my-destination");

            

            producer.publish(msg, listners);

        }catch(Throwable e){

            LL.error(e.getMessage(), e);

        }

    }

Flex client

==========

var cs:ChannelSet = new ChannelSet();

var ch:AMFChannel = new AMFChannel("longPollingChannel","http://172.26.27.94:8084/gravityamf/amf");

ch.pollingEnabled = true;

ch.pollingInterval = 2000;

cs.addChannel(ch);

consumer = new Consumer();

consumer.channelSet = cs;

consumer.destination = "my-destination";

consumer.topic = "my-heartbeat";

consumer.addEventListener(MessageEvent.MESSAGE, messageHandler);

consumer.subscribe();

Error

StoredClassDescriptors array is empty when I try to subscribe from Flex client

Usually this array is not empty

It's my mistake in Flex client, GravityChannel should be used instead of AMFChannel
