Problem/Motivation

This might not be a bug with Drupal, but rather one with Composer. Or perhaps not a bug at all.

Steps to reproduce

While debugging something else, I noticed that in vendor/composer/ClassLoader.php::loadClass(), when loading this class:

Drupal\mysql\Driver\Database\mysql\Connection

The returned path file path is this:

/var/www/html/web/core/modules/mysql/src/Driver/Database/mysql//Connection.php

Notice that there are two slashes in a row. "mysql//Connection.php"

These can be found by creating a conditional breakpoint in ClassLoader inside

function includeFile($file)
{
    include $file;
}

The breakpoint condition can be str_contains($file, '//')

I am using Drupal 9.4.8 with PHP 8.1.11 and composer 2.4.3.

Isn't that one of the problematic classes that had to be worked around in some use-cases? In this case I mean #3290924: [regression] With Drupal 9.4, can no longer call Database::getConnection() from within settings.php due to driver classes not yet in autoloader. And the workaround was to define these namespaces in settings.php. Is that possibly the case with the affected site?

I am not calling Database::getConnection from settings.php. In fact, I have no errors at all. I just happened to see this odd result while debugging something else.

Is only this class affected?

No, it appears any class within that parent folder shows that way, such as 

/var/www/html/web/core/modules/mysql/src/Driver/Database/mysql//Select.php
/var/www/html/web/core/modules/mysql/src/Driver/Database/mysql//Update.php
/var/www/html/web/core/modules/mysql/src/Driver/Database/mysql//Delete.php
/var/www/html/web/core/modules/mysql/src/Driver/Database/mysql//Merge.php

I don't know if it happens for other DB drivers.
