This is a trivial change which allows us (Datadog) to match Java with other languages (Python and Go) in our offering for memory leak profiling. Without this information, we cannot provide a Heap Live Size profiler like described in [1] as we can't get the information about the size of the object sampled as part of the OldObjectSample events.

The patch applies cleanly.
