-----------------------------------------

Hi [~adulceanu],

i can not reproduce the issue on my side, but I had conversation wiht [~ngupta] who could reproduce it.
Seems that problem is because in test, mock instrumentation happens after setting mocked object using reflection. 

Setting object after it has been instrumented, seems to resolve this issue. Change is in patch below.
