I'm getting very confused regarding the different threads on this. But
this webrev:
http://cr.openjdk.java.net/~nloodin/exception-tracing/webrev.01/
shows the intrusive event tracing that I'm sure we said we would
grudgingly accept for 7u but not for JDK 8.

are counting the number of throwables constructed. You might want to
change the name to reflect that. I don't think anyone would want to
write a spec for how many throwables are thrown given that a throwable
can be wrapped, suppressed, rethrown, etc.
