Exception while invoking extension AcknowledgedMessagesClientExtension

[Iain]

Hi,

I am getting an exception when I try and subscribe to the channel "/
**". I have enabled message acknowledgement on the server and client.

On the client, it constantly Connects, Disconnects, Connects,
Disconnects.

On the server, the following happens:

And the server code:

public BayeuxServer bayeuxServer()
{
BayeuxServerImpl bean = new BayeuxServerImpl();
bean.setOption(BayeuxServerImpl.LOG_LEVEL, "3");
bean.addExtension(new
org.cometd.server.ext.AcknowledgedMessagesExtension());
return bean;
}


Any ideas?

Cheers,

Iain

All right I can reproduce, can you please file a bug at http://bugs.cometd.org ?

The issue is the subscription to /** along with the ack extension.
Subscription to non /** works fine.

Working on it.
