Gravity does not reconnect when the connection between app server and JMS breaks/reconnects

I'm running JMS messages from ActiveMQ (standalone, not VM) to Flex using Gravity.

When my application server loses the connection to ActiveMQ it automatically reconnects after a short time and continues to receive messages. However when this happens the Flex clients also lose their connection but never reconnect. The Flex app needs to be restarted to regain the connection.

Flex should reconnect automatically or otherwise nicely handle.

One way to reproduce:
Run ActiveMQ on localhost (or wherever)
Create a grails project
Install GDSFlex
Create Flex project and configure gravity with JMS to connect to ActiveMQ
Send messages to the relevant Topic. They will be handled by Flex.
Break the connection to ActiveMQ eg. by restarting ActiveMQ
Send messages to the relevant Topic. They will not be handled by Flex.
Reload Flex application
Send messages to the relevant Topic. They will be handled by Flex.

Not absolutely sure, but it should be fixed since 2.3.x.
It looks like the same case than server failover when clustering ActiveMQ instances.

Nah it doesn't work. What does work is to disconnect from the channel and then reconnect, like:

consumer.unsubscribe();
consumer.disconnect();
var channelSet:ChannelSet = new ChannelSet();
channelSet.addChannel(ServerConfig.getChannel(Globals.ID_GRAVITY_CHANNEL));
consumer.channelSet = channelSet;
consumer.destination = topic;
consumer.subscribe();

But it doesn't reconnect automatically.
