Brian Geffon commented on TS-2878:
----------------------------------
Np, I'm not sure how the unit test could cover this specific situation, in this
case the structure of URLImpl was changed, so the unit test could never have
caught this situation. But I can add a check to prevent regressions on just
that string.
