BTrace checks only first return in traced method

[mgazizova]

Hello!

I analyzed the report from BTrace-agent and found a zero duration for some methods. These methods have several returns. If traced method use second (or next) written return the @Duration param is 0.

Probably, bTrace checks only first return in method and can't check other. I think it spoils statistic results.
I use openjdk version "11.0.6", BTrace 2.0.2.
