    Sub-instance of me represent a particular Java release and provides and

    access to JDK/JRE files as well and native method implementation and other

    things that are release-dependent.

    There is a guessing mechanism trying to auto-detect path to JRE/JDK. If it fails,

    you may always set javaHome manually (see #javaHome:).

    NOTE: an instance of OpenJDKx and OracleJDKx represent provide access to both,

          plain JRE or full JDK.
