      Description

      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:

      The result is :

      <ServiceException>java.lang.NullPointerException</ServiceException>
      

      With the following log:
