@mcliedtke Can you review this?

[mcliedtke]

Overall LGTM, one small comment on including an additional test assertion

[mcliedtke]

Can you also comment on what branches you believe this change to be added to. Are you targeting for updating 2.13?

[atokuzAmzn]

@mcliedtke good catch on missing check. I have added the extra assertion.
Yes we are targeting to update 2.13

[mcliedtke]

LGTM, I think these changes can be merged. Given the nature of the change, I think merging to 2.13 is pretty safe. @cowtowncoder do you want to handle the merge itself?

[atokuzAmzn]

@cowtowncoder or @mcliedtke
Can we merge this into 2.13?

[atokuzAmzn]

Following up with this merge request @cowtowncoder @mcliedtke

[cowtowncoder]

Ok, I am back from my vacation. @atokuzAmzn If you want this merged against 2.13, please rebase or recreate.
While cherry-picking sometimes works, the usual practice is to start with the oldest branch & merge forward.

This is my first time working with github. I changed the base of this PR but I am not sure if this is what you wanted @cowtowncoder. If needed I can recreate a new PR based on 2.13

[cowtowncoder]

@atokuzAmzn Alas, no: this would merge back all changes from 2.14 -- and not just ones you are making -- so that wouldn't work. I am not 100% sure what'd be the easiest way to change the base for existing PR. Maybe others can suggest something?

But it may be easier to simply create a new PR, if that works?

I created a new PR based on 2.13 here : #322
