>
> java/engine/org/apache/derby/iapi/services/cache/ClassSize.java has a static
> code block which calculates the size of a reference for the architecture.
> This code could be improved by adding garbage collection before measuring
> memory, to give a consistent reading. Also there have been suggestions
> that we use os.arch or sun.arch.data.model to make the measurement more
> reliable, especially on 64bit machines.
