JRockit, was a proprietary Java virtual machine (JVM) originally developed by Appeal Virtual Machines and acquired by BEA Systems in 2002, became part of Oracle Fusion Middleware as part of acquisition of BEA Systems in 2008.
JDK 28.2.3 / 12 April 2012
|Written in||C and Java|
|Type||Java Virtual Machine|
The JRockit code base was discontinued by Oracle, with some features being integrated into the HotSpot virtual machine as part of the mainline development of the Java platform. JRockit only ever supported Java 6, which is now considered an obsolete release.
In May 2011, Oracle announced that JRockit has become free, and confirmed the plan to port JRockit features on OpenJDK.

Since we are converging the JVMs technically it makes sense to treat them as a single "product" with two different incarnations/implementations. Second, by making JRockit free we hope to get more feedback on any regressions in the converged JVM vs current JRockit, which will help our convergence project.
