With this update, the mrj.version system
property is set to 3.2.
The Java implementation in Mac OS X does not draw a distinction
between the Java Development Kit (JDK) and the Java Runtime Environment
(JRE) as on some platforms. Since both development components as
well as the runtime environment are included with a default installation
of Java on Mac OS X, the mrj.version system
property is used to designate the specific overall Java implementation
in Mac OS X.
