YourKit bugs?

I'm presently using YourKit for the first time, to address some memory usage issues. I've had a couple of issues that cause me a bit of concern.

First, it has thrown some stack traces in a window that requests them to be sent to the company. That would be a good sign that they care about their product, but it raises some concerns when combined with my second issue.

Second, the included memory calculations (size of object plus descendants) seem questionable in some cases. In particular, I was surprised to find several items stored in our session having widely varying included sizes when I expected them to be identical. Digging a bit deeper, it looks like the descendant objects add up properly for the larger items, but they add up to far more than is listed for the smaller items.

Has anyone else seen anything similar? Am I missing something, or is there reason to worry about the dependability of the results? Should I push my company to buy another product, even though they've paid for a couple of YourKit licenses already?

Please report the exceptions to support@yourkit.com
It's better to report problems to product developers than disscuss them here.

Regarding retained size calculation: please read "Shallow and retained sizes" section of bundled help. It describes in details the concepts. It's absolute not true that objects of the same type have the same retained size.
