nice, i'll have to see if this can help with situation in instrumentation repo, currently we have some loose assertions to account for similar issue

[tnevolin]

Sorry, everybody.
I need to close it and open a new one to kick EasyCLA test again. I'll put forward link to new one.

[tnevolin]

Never mind. It seems that my personal CLA request got approved. Reopening this again with all passed tests!
