Vertical stripes in wms output when gs:CropCoverage is applied in SLD

Description

I'm using the CropCoverage process to crop my raster file. It is cropped correctly but it renders white, vertical lines in the output (see attached screenshot). This happens only with nearest neighbor interpolation. Input raster is a 3 band aerial. Published with the image pyramid plugin.
