> Spinoff from Tom Burton-West's java-user thread "CheckIndex
> ArrayIndexOutOfBounds error for merged index" (
> http://markmail.org/message/fatijkotwucn7hvu ).
> I modified Test2BTerms to instead generate a little over 10B terms, ran it
> (took 17 hours and created a 162 GB index) and hit a similar exception:
> {noformat}
> Time: 62,164.058
> There was 1 failure:

> The index actually succeeded building and optimizing, but it was only when we
> went to run searches of the random terms we collected along the way that the
> AIOOBE was hit.
> I suspect this is a bug somewhere in the compact in-RAM terms index ... I'll
> dig.
