We ask that fixes be submitted as pull requests to master (and we have not
problem backporting fixes so it appears in the next 15.x build).
Looking at the stack trace the error is in this line:
if (!coverages.isEmpty()) {
ColorModel cm =
coverages.get(0).getRenderedImage().getColorModel();
Are you getting a null rendered image or a null color model?

What NetFlow Analyzer can do for you? Monitors network bandwidth and traffic
patterns at an interface-level. Reveals which users, apps, and protocols are
consuming the most bandwidth. Provides multi-vendor support for NetFlow,
J-Flow, sFlow and other flows. Make informed decisions using capacity
planning reports. https://ad.doubleclick.net/ddm/clk/305295220;132659582;e
