Hey Vitaly,

I solved the issue. As you pointed out,
was quite relevant.

However, you linked to version of this file on master branch. Liberty
branch file looks a little different:

So, fix is already there. It is just only there in master and Mitaka
branches. Maybe we can backport this fix to Liberty EOL release?

Thanks for your help,
Jeremy Freudberg
