Hi,

Check out the Java Memory Profiler:
<http://developers.sun.com/techtopics/emergingtech/>

Also, Sun recently put out this toolset that might give you what you
need: <http://developers.sun.com/dev/coolstuff/jvmstat/>. It is one of
the "Emerging Technologies" made available by Sun:
- <http://developers.sun.com/techtopics/emergingtech/>

I have not made use of these tools yet, so I cannot give any
information on their quality or utility.

I have written one. It sits dormant in the VM until you prompt it for
an ASCII heap dump via CTRL-\, SIGQUIT or CTRL-BREAK in windows. You
can download it from http://www.virtualmachine.de/.
There's instructions how to count class instances with the popular
Unix(*) tools.
