      A DESCRIPTION OF THE PROBLEM :
      The attached program displays the LineChart in red on Java 8 update 101 and below. If I use Java 8 update 102 or later (I've tried 111 and 112) the line is black.

      CUSTOMER SUBMITTED WORKAROUND :
      Use a new mLineChart instance each time - uncomment first line in updateLineChartData() method to see.
