I develop a language plugin, it has lots of unit tests. Starting from the 212.x version of the SDK some of them fail if executed all at once, but they don't fail if executed individually. The kinds of unit tests failing:
Exactly the same unit tests executed all at once on the 211.x version work fine, i.e. all successful.
What could be the cause? Any idea?
P.S. I had another issue with the 212.x and 213.x versions and the cause was a change in the SDK implementation, therefore, I guess, it could be something similar.
