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. |
