The Doctrine Autoloaders don't work from the global namespace in the following context:

Loader::loadClass("\Doctrine\ORM\Mapping\Driver\AnnotationsDriver");

The prefix slash is not matched and the doctrine autoloader fails.

Comment created by @beberlei:

The problem is rather that i want to address a class by its fully qualified name:

$class = '\Doctrine\ORM\Mapping\Driver\AnnnotationDriver';

if(class_exists($class)) {

} else {
    // he cant find it with the \ prefixed
}

The IsolatedClassLoader tries to match the namespace against the class:

string(9) "Doctrine\"
string(46) "\Doctrine\ORM\Mapping\Driver\AnnnotationDriver"

And the strpos prefix check fails on this.

Namespaces in strings are always fully qualified so there is no need for the leading backslash.
