hi,

I created a topic (myBroker) with the MB ui. Then when I try to subscribes
to the topic in JMS it gives this exception.

[2011-02-01 20:09:48,625] ERROR {org.apache.qpid.client.AMQConnection} -
Throwable Received but no listener set: org.apache.qpid.AMQException: ch=1
id=5 ExecutionException(errorCode=UNAUTHORIZED_ACCESS, commandId=8,
description=Cannot subscribe to '1': Permission denied) [error code 403:
access refused]

But however I have given the necessary permissions and it seems the
following check, returns true as well.

if (userRealm.getAuthorizationManager().isUserAuthorized(
                        username, permissionID,

TreeNode.Permission.SUBSCRIBE.toString().toLowerCase())) {
                    // Store subscription
                    RegistryClient.createSubscription(routingKey, queueName,
username, isDurable);

                    return Result.ALLOWED;
                }

Can be reproduce by adding a subscription from the subscription menu.

thanks,
Amila.
