Getting this error while exporting an shapefile to svg (courtesy to iant):

The weird thing is I wasn't getting this error before, but I just suddenly starting getting it after running my application, what could have happened?

Code can be found here: Exporting Shapefile to SVG using Java & GeoTools?
