1.3. Important Notes

Since AMQ 6.3, the AMQ Maven artifacts are available only from the following Maven repositories:

Hence for AMQ 6.3, you need to edit your Maven settings.xml file, replacing the old repo.fusesource.com repository URLs (at https://repo.fusesource.com/nexus/content/repositories/releases and https://repo.fusesource.com/nexus/content/groups/ea) with the new Maven repository URLs.

In AMQ 6.3, the ActiveMQ runtime has been modified so that it is compatible with and can be wired to the JMS 2.0 API bundle. This does not imply that ActiveMQ supports JMS 2.0. In fact, ActiveMQ still supports JMS 1.1 only. This change does mean, however, that it is now possible to deploy an ActiveMQ broker (which is a JMS 1.1 application) alongside a JMS 2.0 compliant application in the same OSGi container. This can be useful, for example, if you want to deploy two different messaging products in the same Apache Karaf container.

In the Apache Karaf container, Jetty (which provides the default HTTP servlet container for Karaf) has been upgraded from Jetty 8.1.x to Jetty 9. This has a significant impact on the Jetty container configuration, affecting settings in the etc/org.ops4j.pax.web.cfg file and in the etc/jetty.xml file. For more details, see chapter "Securing the Jetty HTTP Server" in "Security Guide".
