Description

Hi,

I tried to migrate a TYPO3 6.1.latest project to 6.2.0 (exchanged the 6.1 core to 6.2, clearing all previously files in typo3_src).
After I try to access the frontend/backend, I get redirected to "typo3/sysext/install/Start/Install.php" and am presented with the following
PHP error:

Fatal error: Call to a member function isPackageActive() on a non-object in <docroot>/typo3/sysext/core/Classes/Utility/ExtensionManagementUtility.php on line 101

By digging into the core I found a class inheritance bug, as an object, where the object with the isPackageActive() method is included via a dependency injection into another class, but the initation of the injected object is wrong, meaning the class variable isnt initiated i.e. in the constructor or another
init-method.
It only occurs if you try to migrate a given project from 6.1.latest to 6.2, not if you do a 6.2 from scratch.
