Description
From 4109263 essentially.

Need some way to throttle down the amount of data that would be inside an hprof dump.

format=short or format=long was suggested, but perhaps other ideas need to be investigated also
like filters on which java packages, classes, or methods you don't or do care about?

Maybe the sizes or ages of objects you do or don't care about?

Maybe the method call tree that you care about? (like Jfluid?)

Also a top=n option to limit the size of the summary pages?

EVALUATION Closing this out as not to be done, the work in 6239651 should also provide tools to do this, and the existing jhat tool in JDK 6 (and other tools) allow for searches of the heap information. There is a problem with doing subsets on a large connected graph of data, so the current tack will be to get the entire heap dump in fairly complete form as quickly as possible, then allow for tools to view that data, putting the filtering in the viewer.
