documentation

    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 and provide access to both,

          plain JRE or full JDK.

    [author:]

        Jan Vrany <jan.vrany@fit.cvut.cz>

    [instance variables:]

        javaHome <String> ..... path to either JDK or JRE, ie., path to directory in which

                                * exists bin/java (bin\java.exe) - then javaHome is considered

                                  a path to JRE

                                __or__

                                * exists bin/javac (bin\javac.exe) - then javaHome is considered
