> The method `Arguments::get_default_shared_archive_path()` generates a string containing a path every time it is called. Since this method is idempotent, the string only needs to be constructed once in the lifetime of the VM. This change caches the result of `Arguments::get_default_shared_archive_path()` and ensures the path string is only generated once.
