Hi,
I have noticed that Application.stop/1 calls are no longer being reported by erlang’s :error_logger in the same way with version 1.15.0. It was working with version 1.14.5.
See this sample module for an example. I use poison as the application to stop, but it could be any application that has started:
defmodule GenEventTester do
@moduledoc """
Documentation for `GenEventTester`.
"""
@behaviour :gen_event
require Logger
@impl :gen_event
def init(_) do
Logger.notice("init/1 has been called")
{:ok, %{}}
end
@impl :gen_event
def handle_event(msg, state) do
Logger.notice("handle_event/2 has been called: #{inspect(msg)}")
{:ok, state}
end
@impl :gen_event
def handle_call(msg, state) do
Logger.notice("handle_call/2 has been called: #{inspect(msg)}")
{:ok, :ok, state}
end
end
Running this with Elixir 1.14.5:

Interestingly, the gen_event behaviour is being used somewhat, as the init/1 callback is called.
Does anybody know how to get the handle_event/2 callbacks to be called with Elixir 1.15.0, and/or know why this is happening?
