    [HDP] java64_home not pointing at default-installed JDK for plugin

    At this time HDP's java64_home property defaults to /opt/jdk1.6.0_31.
    However, the now-default openjdk element installs to /usr/lib/jvm/java-openjdk.
    If nodes are connected to the internet at cluster spinup time, this does not
    cause an overt error, but querying for JDK location will return error code 2,
    resulting in no -j argument being passed to 'ambari-server setup -s', which in
    turn will result in a download of Oracle's JDK and successful installation. In
    the case that the nodes cannot connect to the internet (which should be a
    success case with a pre-installed VM image,) cluster creation fails at this
    stage.

    This patch updates java64_home to the default JAVA_HOME from the openjdk
    element.
