TYPO3 Core

A method cannot be abstract and static at the same time. A child class can have a static method with the same name, but it will not be an implementation like you try to enforce with an abstract method.
There is late static binding in PHP 5.3+, but this is slightly different.

Patch set 1 for branch master of project Packages/TYPO3.CMS has been pushed to the review server.
It is available at https://review.typo3.org/26777

How-to Reproduce¶

Use PHP 5.4

Add this to AdditionalConfiguration.php:

$GLOBALS['TYPO3_CONF_VARS']['SYS']['errorHandlerErrors'] = E_ALL ^ E_NOTICE;
$GLOBALS['TYPO3_CONF_VARS']['SYS']['exceptionalErrors'] = E_ALL ^ E_NOTICE ^ E_WARNING ^ E_USER_ERROR ^ E_USER_NOTICE;

Try to show Backend Login form.
