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.

STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
Run the attached program and look at the colour of the LineChart.

EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
The Line Chart should be red.
ACTUAL -
The Line Chart is black.

REPRODUCIBILITY :
This bug can be reproduced always.

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