> After copying here to jira, cannot found difference, but by checking from
> original junit xml, there is a whitespace difference in the lines
> (represented as hex values), between 1 (x31) and 4 (x34). See [^diff] .
> Original golden file contains horizontal tab (x09), actual output contains
> space (x20).
> The serious thing is that the separator changes to x20, which is wrong, but
> then in the same line, it changes back to x09.

> Tried to reproduce it by running the failing batch of qtests locally, but no
