Style with Interpolate function causes NullPointerException on GetLegendGraphic

Issue Type:	Bug
Affects Versions:	2.13-beta
Assignee:	Unassigned
Components:	WMS

Priority:	Medium
Reporter:	Gnafu

I’m using the Interpolate function to pick a color based on a feature property.
The style works as expected but the GetLegendGraphic requests fail with a NullPointerException.

Here is how to reproduce:

From the default GeoServer data dir, duplicate the “poly_landmarks” style
Delete row 44 (PolygonSymbolizer-> Fill -> CssParameter -> ogc:Literal)

Paste the following in row 44:

                &lt;ogc:Function name="Interpolate"&gt;
                  &lt;!-- Property to transform --&gt;
                  &lt;ogc:PropertyName&gt;LAND&lt;/ogc:PropertyName&gt;

                  &lt;!-- Mapping curve definition pairs (input, output) --&gt;
                  &lt;ogc:Literal&gt;0&lt;/ogc:Literal&gt;
                  &lt;ogc:Literal&gt;#ff0000&lt;/ogc:Literal&gt;

                  &lt;ogc:Literal&gt;255&lt;/ogc:Literal&gt;
                  &lt;ogc:Literal&gt;#ffff00&lt;/ogc:Literal&gt;

                  &lt;!-- Interpolation method --&gt;
                  &lt;ogc:Literal&gt;color&lt;/ogc:Literal&gt;

                  &lt;!-- Interpolation mode - defaults to linear --&gt;
                &lt;/ogc:Function&gt;

Save and assign it to the tiger:poly_landmarks layer
Issue a GetLegendGraphic request for that layer with the new style:
http://localhost:8080/geoserver/ows?service=WMS&request=GetLegendGraphic&format=image%2Fpng&height=12&width=12&layer=tiger:poly_landmarks&style=test_intrepolate&version=1.3.0&SLD_VERSION=1.1.0&LEGEND_OPTIONS=forceLabels%3Aon%3BfontSize%3A10&SCALE=4514

The result is :

&lt;ServiceException&gt;java.lang.NullPointerException&lt;/ServiceException&gt;

With the following log:
