Note

The first few versions of JRockit were made available as "Virtual Machines for Java", not JVMs. The key difference is that only a virtual machine certified by Sun (now Oracle) to be compliant with the Java standard is allowed to be called a JVM. Furthermore, if the VM is not certified, it may not use the Java trademark. At that time, in order to be accepted as a Sun certified JVM, a key differentiator, known as "value add" was required. In our first attempt to become a proper Java licensee, we had specified "superior performance" as our value add. While technically true, it was not deemed to be a valid value add, so we exposed some of the online manageability aspects of the JVM instead. This is what became the JRockit Management Console.
