ZF-6798: Registered autoloader doesn't allow to use class_exists() function.


If Zend_Loader_Autoloader is registered as autoloader, then class_exists() method generates an error instead of returning false. See [ZF-6607] for an example.


Didn't see this earlier when I posted ZF-8364 but I think we've run across the same issue. I attached a patch on my issue that should resolve the problem, I believe.

Thanks! Adam
