Tenured Promotion Composition?

[Andrei Pozolotin]

    Ramki, Jon, hello;

    1) Can you please suggest correct way to obtain Tenured Promotion
    Composition?

    That is, for each ParNew collection event I would like to get a
    print out
    of a class histogram which shows, say top 10 classes
    responsible for 80% of promotion chunk, by memory footprint;

    2) JVM TI does not seem to have this info:
    http://java.sun.com/javase/6/docs/technotes/guides/jvmti/

    3) JDK 6 command options seem not offer this either:
    http://www.md.pp.ru/~eu/jdk6options.html

    ???

    Thank you,

    Andrei
