* only show the checkboxes that have any influence on the diagram
* add additional brokers that are known but are not part of the cluster (at this moment)
* made construction of master-slave pair slightly more readable
* simplified construction of dummy broker icon
* show properties of current broker with the correct node of the diagram
* use the new styling for the current broker icon
* show the broker name instead of "broker"
* replace style ThisBroker with ThisMasterBroker+ThisSlaveBroker
* do not show quotes around address- and queue-names
* show the broker name without port number when the port number is the default one
* properly document the icon choices
The auto-create-jms-queues, auto-delete-jms-queues,
auto-create-jms-topics, and auto-delete-jms-topics address settings
were deprecated in ARTEMIS-881 way back in 2016. There's no need to keep
them in the default broker.xml at this point.
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.
