Elasticsearch-php produces lots of warnings with php 7.4 preloading enabled.

Summary of problem or feature request

I use elasticsearch-php within a symfony project (symfony 4.4). Elasticsearch-php produces lots of warnings with php 7.4 preloading enabled.

Example log line:
NOTICE: PHP message: PHP Warning: Cannot declare class \Elasticsearch\Endpoints\Cluster\Nodes\HotThreads, because the name is already in use in /code/xx/vendor/elasticsearch/elasticsearch/src/autoload.php on line 11

This line is repeated for every class_alias defined in the mentioned autoload.php

System details

• Operating System: Alpine Linux
• PHP Version: 7.4.6
• ES-PHP client version: 7.7.0
• Elasticsearch version: 7.7

I'm seeing the same issue with PHP 7.4.7.

@hoebelix, @adri we are working on #1051 but I would like to understand the preload configuration that you are using. Thanks!

I just use the default symfony 4.4 preload configuration:

opcache.preload=/var/www/var/cache/prod/srcApp_KernelProdContainer.preload.php
opcache.preload_user=www-data

Same for me, default symfony 4.4

@hoebelix, @adri thanks for the information. The issue has been fixed in #1051. I'll release it soon in 7.9.
