is -javaagent considered harmful?

Hi all,

Well it turns out that Java does have a "sizeof"... you can access it via an
Java agent which gets a handle into java.lang.instrument.  But this requires
you to run a Java Agent JAR.

This is clearly suitable for experiments or profiling, but would it be
possible to run this full-time without performance problems?

Thanks,
-ryan
