TYPO3 Core

Hi,

The TYPO3 frontend and sometimes the backend throws many erros with the message:

ReflectionException: Internal error: Failed to retrieve the default value in 
.../typo3_src-6.2.25/typo3/sysext/extbase/Classes/Object/Container/ClassInfoFactory.php on line 68

In TYPO3 6.2.* and TYPO3 7.* with PHP 5 and PHP 7

I can't find something about that and this message doesn't show me a place,
where i have to set the default value.
Often there is no one of my own classes listet in the stacktrace.

It's not very funny to work in the development, with that messages on top...

TYPO3 7 also throws many messages in the backend like that:

TYPO3\CMS\Backend\Routing\Exception\RouteNotFoundException: 
Unable to generate a URL for the named route 
"ajax_ExtensionBuilder::wiringEditorSmdEndpoint" because this route was not found. 
in ...../typo3_src-7.6.9/typo3/sysext/backend/Classes/Routing/UriBuilder.php on line 73

and that for many routes: web_layout, web_list, web_func, web_info, user_setup ...

these many errors are responsible for some headaches and lots of wasted time :D

I'm very interested to your reply!
