[erlang-questions] Erlang release and config includes

[Siri Hansen]

Hi Alexander!
This is a bug in application_controller:change_application_data/2, which is
called from the release_handler. It occurs for applications that are added
in an upgrade only (i.e. not for already loaded applications).
It will be corrected in OTP-17.1.
Thanks for the report!
