The latest Cumulative Patch release for both JBoss Enterprise Application Platform (EAP) v4.2 & v4.3 are now available. Cumulative Patches (CPs) are incremental updates that fix all known issues and are typically made available on a quarterly basis to all customers.

Java SE 6 Support
With today's release, we're please to announce official support for Java SE 6 for JBoss Enterprise Application Platform v4.3 using the Sun JDK. Congratulations to the JBoss team for making this happen! We've updated our list of Compatible & Certified Configurations to reflect this.

More Certified Configurations
You'll also notice that we've now extended the number of Certified operating system, chip architectures & JVM combinations from 16 to 29. Since we can't possibly test every combination, we continue to support any configuration that runs on a JVM that we've certified to, no matter the OS/Chip/JVM combination; we call these Compatible Configurations as we rely on the compatibility of the underlying JVM. We try to be transparent and we want you to know what we've officially fully tested against, hence the distinction between 'Certified' & 'Compatible' configurations.

IBM Mainframe Support
Are you running your Java application on a mainframe? Looking for an alternative application server? We've supported JBoss Enterprise Application Platform on mainframes as a Compatible Configuration for some time, and now, based on customer requests, we've officially added mainframes to our list of Certified Configurations with IBM System z running Red Hat Enterprise Linux. If you're looking for reasons to switch, whether you're a mainframe user or not, we've conveniently listed them for you here.

Are these the only configurations we test? Nope. This isn't our complete list, but it does represent the list we run our full battery of quality, integration and performance tests on for every release. If you're wondering what we test, we cover the topic in this whitepaper about the making of JBoss Enterprise Middleware. Also, Andy Miller, one of our JBoss Engineering VPs, provides detail in this blog post from earlier this year.

If you have configurations that you'd like us to add or are interested in learning more about what tests we run, just let us know by sending a note to jbossquestions@redhat.com.
