This issue occurs when you have a key with upper case characteres like {{appOptions}}, and you try to use {{$this->getOption('appOptions')}} inside the Bootstrap.

It seems to be related to a missing {{strtolower}} on the method {{hasOption}} of the class {{Zend_Application_Bootstrap_BootstrapAbstract}}.

As so, I think the method {{hasOption}} should be changed to include {{return in_array(strtolower($key), $this->_optionKeys);}} this way the {{getOption}} method will behave the same way on both {{Zend_Application_Bootstrap_BootstrapAbstract}} and {{Zend_Application}}, as expected.

This issue seams related to ZF-7742, where the same fix has been applied Zend_Application for solving a similar issue (and should have been applied also to {{Zend_Application_Bootstrap_BootstrapAbstract}}

As far as I know this affects all releases of ZF.

A simple workaround is to override the hasOption method when extending {{Zend_Application_Bootstrap_Bootstrap}}.
