Obtaining methods executed at least once?

yes, I did consider using JVMTI. Unfortunately, there's no proper event
for this, and handling all JVMTI_EVENT_METHOD_ENTRYs is very expensive,
even if it is "just" looking up jmethodID's in a map most of the time.

Thus I was thinking about forcing compilation (-XX:-UseInterpreter) and
then using the compilation log. I am unsure, however, if this really
gives me all methods, i.e., if -XX:-UseInterpreter is respected all the
time.

Best wishes,

Andreas
