Indeed, makes sense that those are the two possible approaches to fix
the problem.

Do you have an idea what could cause this kind of distortion? I am now
strongly suspecting this a bug in JAI and not resolvable in geotools,
would that be possible?
Mind, this is quite likely the case, there is probably something in
the warp math
that has fragile numeric behavior when the raster coordinates got up
on very
high values.
This could likely be fixed in jai-ext.
Another possible approach would be to "fix" image mosaic so that it
does not
generate these huge coordinates to start with.
Right now it's using a global "grid to world" to represent the output,
but I believe it could be using a "reduced" one, local to the
requested area,
that would position images in raster space location closer to the origin,
and thus avoid this issue without causing performance regressions.
Just an idea ;-)
