Most of the the heap dump will be filled with stuff like java.util.String!blahjava.util.ArrayList!

Though the heap dump would have messages in flight at the time. It's obviously not as useful if you are just trying to grab messages for a specific person.

Frankly the most useful part might be any in-memory secret keys, which could be useful for breaking deeper into the system.

Plenty of info from a live heap dump if you know what you are doing.

But these guys are only interested in "journalists" not people who spent decades digging into ad server heap dumps
