Judging from the source:
http://svn.osgeo.org/geotools/tags/2.5.4/modules/library/render/src/main/java/org/geotools/renderer/lite/StreamingRenderer.javaa NPE at line 1580 can only occur if the data you're trying to renderer
does not have any geometry column. How this can happen, I'm not sure,
but I invite you to look into whatever is providing the data.
