VMware vFabric tc Server to Continue Support of Java 6

Oracle has announced the formal end of life (EOL) of Java 6 coming up in February of 2013. Given that a significant portion of VMware vFabric Suite customers are still running applications that use Java 6, VMware has chosen to continue  support for vFabric Suite running Java 6 applications.  This includes a la carte support only contracts for Apache Tomcat and Apache HTTPD. Current versions will not expire their support for Java 6 with the EOL in February, 2013.

Additionally, VMware will continue testing and validating future versions of the vFabric Suite on Java 6 until further notice.

What this means for customers

vFabric customers that chose not to update their applications to Java 7 will still enjoy the same level of support from VMware for their vFabric middleware stack that powers their Java 6 applications, even past its end of life. It also means that Java 6 will continue to be a testing requirement for future versions of vFabric Suite. Customers not interested in updating their applications to Java 7, can continue to trust their vFabric upgrades from VMware.

For customers purchasing a la carte VMware support only for Apache Tomcat or combined support only for Apache Tomcat and HTTPD, they will not violate their support contract by continuing to run applications using Java 6.

What’s New in EM4J 1.1?

Elastic Memory for Java (EM4J) 1.1 is a memory management toolkit for Java in vSphere, focused on enabling customers to confidently achieve greater memory efficiency for their Java workloads.

EM4J is a relatively new technology developed here at VMware which was created to solve the problem of memory reclamation in VMs predominantly running Java. This week, as part of the overall vFabric Suite 5.1 release, we introduced EM4J 1.1 which builds on that foundation with new monitoring capabilities in vCenter designed specifically to support Java workloads, as shown in this screenshot. First, however, if you are not familiar with EM4J, it may be helpful for a more detailed background on EM4J itself. If you are already familiar with it, you can skip to the section below on EM4J 1.1.
