TYPO3 Core

When e.g. installing tt_news version 3.4.0 (compatible to TYPO3 CMS 6.0.0) a fatal error will be shown since tt_news uses a class in ext_tables.php that requires the autoloader's registry information.

The following happens on installing an extension:

• flushing the caches (including the class loader cache)
• redirecting to list view of extension manager
• triggering shutdown method in ClassLoader
• updating cache if $cacheUpdateRequired is set

This updates the autoloader registry with old data since the extension's ext_autoload.php has not been considered at that time.

The issue is fixed by explicitly calling a new refresh method in the ClassLoader.
