Relativizing (or, to use IT-speak, virtualizing) the class histogram
reporting mechanism to a per-generation report might provide useful
profiling/debugging information for some kinds of customers/users.

SUGGESTED FIX Here's a preliminary webrev (sans the changes for 6797870):- http://analemma.sfbay.sun.com/net/spot/workspaces/ysr/genhisto/webrev This will of course change some as soon as the changes iof 6797870 are imported, at which time an updated webrev will be posted.

EVALUATION Will, like 6797870, need CCC approval before it becomes officially supported. Will also need to be reviewed by the serviceability and tools groups.
