[DCOM-47] When using different class loaders Created: 07/Apr/11  Updated: 27/Dec/11  Resolved: 14/Sep/11

ClassLoader::classExists($class); will fail if different class loader is used which does not return any boolean value. This includes Symfony2 UniversalClassLoader

I have never used this function before because native PHP method class_exits($class, true) first will try to autoload. But if the class does not exist
and you are using Doctrine\Common::ClassLoader and you call class_exists($class) it will trigger fatal error. This behavior makes it impossible to make code compatible
with different class loading mechanisms for Doctrine2

This is known and documented in the code: https://github.com/doctrine/common/blob/master/lib/Doctrine/Common/Annotations/Parser.php#L110

Since Annotations package changed a lot since the bug was opened and today, I'm closing the ticket as "Cannot reproduce".

Please reopen it if the issue is still valid with a testcase.

Still a problem! Especially since this is used by ORM (https://github.com/doctrine/doctrine2/commit/3aea203b9ca77df65f55f036080a9af653194cbf)

Class loader doesn't have to return bool (and usually DOES NOT), so even though it has loaded the class, classExists will return false. Please pull this https://github.com/doctrine/common/pull/88
