1.1.9 Version Information
J/Link provides three symbols that supply version information. These symbols provide the same type of information as their counterparts in Mathematica itself, except that they are in the JLink`Information` context, which is not on $ContextPath, so you must specify them by their full names. These symbols are new in J/Link 2.0.
J/Link version information.
The ShowJavaConsole function, described in a later section, will also display some useful version information. It shows the version of the Java runtime being used and the version of the portion of J/Link that is written in Java. The version of the J/Link Java component should match the version of the J/Link Mathematica component.
