Hi Jakub,
*
We can get this data from actual stack trace when code was visited in a
coverage counters spots (places analyzed by JaCoCo). An extension of the
ClassProbeAdapter and changes in org.jacoco.core.internal are needed.
I don't think this is the correct place: ClassProbeAdapter is used at
the time of instrumentation or analysis. It is not invoked at execution
time (only indirectly when using on-the-fly-instrumentation and classes
are loaded the first time).
Execution is recorded by bytecode probes inserted by the instrumentation
process, please see http://www.jacoco.org/jacoco/trunk/doc/flow.html
Regards,
