Class 'JToolBarHelper' not found #14330

Steps to reproduce the issue

Install some extension, in my case it was Phoca Photo. After installing it and going to the extension I get this error:
Class 'JToolBarHelper' not found

Expected result

JToolbar classes will be automatically loaded

Actual result

JToolbar classes are not automatically loaded, they must be individually loaded, e.g. by:

if(!class_exists('JToolbar')) {
   require_once JPATH_SITE . '/libraries/cms/toolbar/toolbar.php';
if(!class_exists('JToolbarHelper')) {
   require_once JPATH_SITE . '/libraries/cms/toolbar/helper.php';

System information (as much as possible)

Joomla! 4, PHP 7, MySQL 5

The class' correct cased name is JToolbarHelper, not JToolBarHelper, and has been such since 3.0.0 (same applies to all JToolbar* classes). The casing is important with our autoloader because it will split the class name based on CamelCasing if it needs to try and load a file that hasn't yet been loaded.

JToolBarHelper will try to find a file at libraries/(cms|joomla|legacy)/tool/bar/helper.php whereas JToolbarHelper will use libraries/(cms|joomla|legacy)/toolbar/helper.php.

Closing as a non-issue.
