RFR(M): 8160299 - Test8015436 doesn't check which method was executed

[Dmitrij Pochepko]

Hi,

please review fix for 8160299 - Test8015436 doesn't check which method 
was executed

Test wasn't strict enough and test output which reflects main test logic 
was unchecked. This fix adds simple driver class which performs 
respective output checks.

I've tested this fix on linux-amd64.

Thanks,
