Exception when reading signed 16 bit images

As of r4804, attempting to read a signed 16-bit image throws the following exception:

Exception in thread "main" java.lang.IllegalArgumentException: Raster ShortInterleavedRaster: width = 384 height = 384 #numDataElements 1 is incompatible with ColorModel ColorModel: #pixelBits = 16 numComponents = 4 color space = java.awt.color.ICC_ColorSpace@347124 transparency = 3 has alpha = true isAlphaPre = false
	at java.awt.image.BufferedImage.<init>(
	at loci.formats.AWTImageTools.openImage(
	at loci.formats.FormatReader.openImage(
	at loci.formats.ImageReader.openImage(

This can be reproduced with deltavision/ome/Antarctic_Diatom_D3D_01.dv (among others).

(In [4874]) Use USHORT instead of SHORT for 16-bit integer SignedColorModel. Fixes #359. This is consistent with the code from before r4804, but does not seem logical. Further investigation is warranted into the ramifications of this approach.
