Good point. I thought about that, but taking into account 3 different 
configurations we have (Client VM, Server VM & Tiered VM), it's not 
trivial to reliably detect from the log what compiler was used.

I'll add VM flavor detection in a separate change and then fix this 
change to limit newly added logic only for C1 compilations.

Best regards,
Vladimir Ivanov
