> I have a situation where I can reliably reproduce an NPE during assembly in
> one dev environment but not in another. Probably the most notable difference
> between the environments is that the working one is running Windows and the
> non-working one is running Linux, but it's not clear why that should matter.
> The project is unfortunately part of a large multi-module project so I can't
> readily attach it here and I haven't yet attempted to boil it down. So
> hopefully this stack trace will help:
