cache_classes cache crashes
with your new implementation of cache_classes you have crashed extbase. If form has Errors (Validators) extbase calls the errorAction. When calling:
I get following error in FE:
Fatal error: Cannot redeclare class TYPO3\Sfvalidator\Controller\PersonController in /Applications/MAMP/htdocs/typo3_git/typo3conf/ext/sfvalidator/Classes/Controller/PersonController.php on line 107
If I debug within getControllerActionName the name was resolved correctly. But when I debug getControllerActionName in Request-Object then I get the error with redeclaration. There seems to be some magic I don't understand. Maybe it is because of "new" in getReferringRequest()?!
