[TYPO3-dev] Extbase Reflexion: Parameter is not optional Issue since PHP upgrade

[g4-lisz at tonarchiv.ch]

Hi there,

since i upgraded my PHP version from 5.3.13 to  5.3.16 i get the 
following error message:

Core: Exception handler (WEB): Uncaught TYPO3 Exception: Parameter is 
not optional | ReflectionException thrown in file 
/var/www/typo3_src-4.6.7/typo3/sysext/extbase/Classes/Reflection/Service.php 
in line 459

Extbase version is 1.4.3 on T3 V 4.6.7.

How can I solve this?

Cheers,
Till
