This rings a bell. In my notes (maybe from the 4.1 days) I found:
bug: trying to wrap StructureDS in VariableDS
add test to line 85 in DatasetConstructor:
else if (!(v instanceof VariableDS) && !(v instanceof StructureDS))
I think I would have mentioned this to the developers. I'm not sure if
they corrected the problem, but it might be a place to start.

I'm trying to create a union aggregation between two files.
