The media team audited the copyright changes and realized:

1) Some of the files that have not been modified by JavaFX, but which were imported directly from gstreamer, had copyright changes applied to change Sun --> Oracle. Since we didn't otherwise touch these files, they should have been excluded from the update. The list of files that need to be reverted are:

    jfxmedia-native/gstreamer/3rd_party/glib/glib-2.22.2/gio/*
    jfxmedia-native/gstreamer/gstreamer-lite/gst-plugins-good/sys/sunaudio/*

A second issue was split off into a separate JIRA -- RT-16907 -- since #1 will be a simple reversion of the above files.
