You said yours were for land use. (I hope neither you nor your company are selling any of these map programs as a reusable component.) Anyway, the F-22 avionics systems would (should) have had a requirement for crossing the IDL as well as functioning at all Lat/Longs and altitudes. If the testing phase was allocated enough resources, which almost never happens, this might have been avoided. Although now I see other replies which doubt this really ever happened. Maybe this story is just another "tech journalist" getting the details wrong, which almost always happens!
For a fact all the F-22s returned, and news reports the day after it happened said it was a "software issue". I saw some blogs by military types talking about the "date line" issue before the story hit the media, so I wouldn't doubt it happened.
If this did happen, it would be exactly the kind of thing the military would *not* publicize. Not only because of the embarrassment, but also to prevent tipping off the world about our weaknesses. I saw a video when I was in the Air Force 25 years ago that gave a very similar scenario as a reason why even apparently trivial information can tip off the bad guys about major components of our capability, and thus these "little" things are often classified.
