ProxyGenerationException proxying the same generic interface multiple times #88
Description
I've made a gist to demonstrate the ProxyGenerationException I get when trying to mock an interface with multiple observers.
The issue seems to only occur when running at least 3 observers (2 is fine strangely).
Test Outcome: Failed
