The heap profile summary displays incorrect sizes for variables length VM objects (the sizes displayed is 0).

For the benefit of the lurkers, the metadata generated by the profiler limits the set of variable length objects to primitive array types. Certain vm-internal objects have a variable length component and that creates an impedance mismatch.

The tentative solution to this problem is to replace the variable length objects (which are all vm-internal objects) with fixed length objects that indirect to a primitive array where the variable length data is stored.

I think this refers to a command line flag that no longer exists. Heap profiles from the service protocol accurately track variable length objects.
