I'm surprised to see adding a performance counter for an "external"
instrumentation agent to use. I understand that we agree that dynamic
bytecode instrumentation is a more appropriate approach to instrument
and count the number of thrown throwables. I guess I am missing the
big picture how you want the serviceability tools (jstat etc) to work
with the perf counters and tracing events.
