If anyone's still interested, irfanview 4.50 32-bit (on windows) opens the image and shows a very large, color, arial view of some rural, green countryside.

Using ImageMagick (IM) identify - the jp2 is 8 bit grayscale with alpha. AFAIK IM uses the same libopenjp2 library as Gimp. However, using XnViewMP the image displays as RGB. Converts to a large tiff (with alpha) which does open (with complaints) by Gimp 2.10.14 (using kubuntu 18.04) At least that will get the image into Gimp.

Re: [Gimp-user] loading jp2 images
This is simply not true. GIMP has been able to open jp2 files for quite some time. It simply means that you're missing jp2 filetype from your GIMP build.

Re: [Gimp-user] loading jp2 images
That's a JPEG2000 format image. It allows larger colour depth and lossless compression, compared to JPEG. Gimp up to 9.2 couldn't open them. I doubt 2.10 can. You can convert them to JPG or probably to TIF and those are both openable.
