I think we can just replace ColorModel based calculation of the pixel value with SurfaceData.pixelFor(). The usage of ColorModel is intended for old Solaris platforms which are not supported any more. Please find the new version here: http://cr.openjdk.java.net/~dmarkov/8214109/webrev.01/ <http://cr.openjdk.java.net/~dmarkov/8214109/webrev.01/>
Also I ran all regression tests and didn’t observe any new failures.
