[OpenJDK 2D-Dev] [9] Fix for JDK-6427331 : NullPointerException in LookupOp.filter(Raster, WritableRaster)

[Ajit Ghaisas]

Thanks Prasanta.

I checked filter() methods of following classes -

AffineTransformOp, ColorConvertOp, ConvolveOp, LookupOp, RescaleOp and BandCombineOp.

They do not have this issue of accessing null destination buffer/raster.

+1. Just check other op file like Rescale, Convolve if similar problem exists there too.

Hi,

 

   Bug : https://bugs.openjdk.java.net/browse/JDK-6427331

   Issue : If destination raster is provided as null to  java.awt.image.LookupOp.filter(Raster src, WritableRaster dest),

                according to Javadoc, a new raster should be created. Instead, it results in NullPointerException.

   Request you to review.
