TIFF/GeoTIFF decoder bit depth problem [JAI 1.1, Tools 1.1.3, Windoze XP]

[jai-interest-2]

I have 2 image files:  one is a regular TIFF @ 8 bit depth, the other is a GeoTIFF @ 16 bit.

This 1st one displays correctly, the 2nd one is all BLACK.  Writing to a DisplayJAI.

Is this a known problem?  Verion:  "JAI 2006-09-11 17:23:56.159-0700"
