I have published one band raster data representing wind direction like Image Mosaics.
They are in EPSG:4258 with a BBOX [-16.058210564139415,32.96955965348397,39.2896078071642,80.02803653793978]
I create a style that represents the wind direction with arrows, in function of the pixel values (see attached file wind_style_1.xml).
When i call the layer with this WMS
I expect to get an empty image for that BBOX and for that TIME, but I get an unexpected exception (see the full stack trace in "error.txt" file in attach).
I replaced in the first style "TextSymbolizer" with "PointSymbolizer" like in wind_style_2.xml but the issue still remain.
The problem happen only for the styles linked. If I use a style with the RULE "RasterSymbolizer" I have no exception for the same layer.
If I publish the same raster with the same style In a geoserver version 2.7.1 that I use for other projects it works properly (this geoserver is running with 1.7.0_65 (OpenJDK 64-Bit Server VM) and Postgresql server version 9.2).
