Currently the broker detects the presence of the web console by looking
for the name of a file (i.e. console.war). This is fragile because if
the file is renamed for any reason then the broker won't print the
status of the web console when it starts.
This commit improves web console detection by inspecting the
<display-name> tag in the war file's WEB-INF/web.xml. By default it
looks for "hawtio", but this can be customized using the system property
"org.apache.activemq.artemis.webConsoleDisplayName".
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.
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.
Allow replication only certain addresses with mirror controller.
The configuration is similar to cluster address configuration.

The commit includes the following changes:
- Don't drop the connection on subscribe or publish authorization
failures for 3.1 clients.
- Don't drop the connection on subscribe authorization failures for
3.1.1 clients.
- Add configuration parameter to control behavior on publish
authorization failures for 3.1.1 clients (either disconnect or not).
Mainly refactoring the address docs. This commit has the following
changes:
- Remove examples for discouraged use-cases (e.g. using anycast and
multicast on the same address).
- Reword to use configuration terms wherever possible. For example,
instead of saying "point-to-point" (which is not a configuration term)
say "anycast". References to things like "point-to-point" and
"publish-subscribe" are still there since users are familiar with these
terms. They're just used much less often.
- Remove duplicate explanation of exclusive queues.
- Remove duplicate explanation of auto-create and auto-delete elements.
- Re-create graphics and include the master SVGs for potential updates
later.
- Give non-destructive queues its own chapter.
- Add details about specifying routing type using a message property.
- Update the styling on the user manual's cover page to look better.
- Lots of re-wording for clarity's sake.
- Re-order sub-sections for clarity's sake.
- Break up the address model and the settings documentation. The
settings documentation is large and deserves its own chapter. The
original anchor link is still available with a link to the new chapter.
In general the address-specific documentation should be much more clear,
concise, and consistent now.
JGroups 3.x hasn't been updated in some time now. The last release was
in April 2020 almost 2 years ago. Lots of protocols have been updated
and added and users are wanting to use them. There is also increasing
concern about using older components triggered mainly by other
recently-discovered high-profile vulnerabilities in the wider Open
Source Java community.
This commit bumps JGroups up to the latest release - 5.2.0.Final.
However, there is a cost associated with upgrading.
The old-style properties configuration is no longer supported. I think
it's unlikely that end-users are leveraging this because it is not
exposed via broker.xml. The JGroups XML configuration has been around
for a long time, is widely adopted, and is still supported. I expect
most (if not all) users are using this. However, a handful of tests
needed to be updated and/or removed to deal with this absence.
Some protocols and/or protocol properties are no longer supported. This
means that users may have to change their JGroups stack configurations
when they upgrade. For example, our own clustered-jgroups example had to
be updated or it wouldn't run properly.
