You can make it work for you, but you'll have to do a bit of engineering
(I'm a little pressed for time at the moment). There's nothing
particularly 1.2-flavored about Profiler, except for its use of the nice
JVMPI interface for starting it and stopping it.
Take a look at the profiler::NotifyEvent method. If you were to pull the
(event->event_type == JVMPI_EVENT_JVM_INIT_DONE) stuff out into
procedure A, the (event->event_type == JVMPI_EVENT_JVM_SHUT_DOWN) stuff
out into procedure B, and take over the initialization stuff from
profiler::JVM_OnLoad() - you'd have a profiler you could start
(procedure A) and stop (procedure B) with calls from your own code. It's
not as nice as automatically loading a profiler, but JDK1.1 doesn't give
us that option.
