MQTT 3.1 and 3.1.1 clients using a clean session should have a
*non-durable* subscription queue. If the broker restarts the queue
should be removed. This is due to [MQTT-3.1.2-6] which states that the
session (and any state) must last only as long as the network
connection.
This is caused by too many entries on the HashMap for ThreadLocals.
Also: I'm reviewing some readlock usage on the StorageManager to simplify things a little bit.
JMSTestCase is deprecated anyway.
in its older form many many years ago a server would be reused over
between tests.
what forced us to make such verification to avoid messages from one test
leaking into the next.
This was because a server startup was expensive many years ago (less
efficient code and the hardware available 10 years ago)
with the current state of things this is not needed as the server will
be started from scratch on every test
It would be useful to be able to cycle the embedded web server if, for
example, one needed to renew the SSL certificates. To support
functionality I made a handful of changes, e.g.:
- Refactoring WebServerComponent so that all the necessary
configuration would happen in the start() method.
- Refactoring WebServerComponentTest to re-use code.
It would be useful for security manager implementations to be able to
alter the client ID of MQTT connections.
This commit supports this functionality by moving the code which handles
the client ID *ahead* of the authentication code. There it sets the
client ID on the connection and thereafter any component (e.g. security
managers) which needs to inspect or modify it can do so on the
connection.
This commit also refactors the MQTT connection class to extend the
abstract connection class. This greatly simplifies the MQTT connection
class and will make it easier to maintain in the future.
Allow replication only certain addresses with mirror controller.
The configuration is similar to cluster address configuration.

The control existing in Redistributor is not needed as the Queue::deliver will already have a control on re-scheduling the loop and avoid holding references for too long.
When running a UDP connection factory you have to either keep it running, or close it so the UDP thread is closed.
this is an issue for the testsuite as we validate for leaked threads. This needs to be fixed on the test.
The MQTT 5 (and 3.1.1) specification states:
Until it has received the corresponding PUBREL packet, the receiver
MUST acknowledge any subsequent PUBLISH packet with the same Packet
Identifier by sending a PUBREC. It MUST NOT cause duplicate messages to
be delivered to any onward recipients in this case [MQTT-4.3.3-10].
The broker prevents a duplicate message, but it doesn't respond with a
PUBREC. This commit fixes that.
