It turns out that the standard Doctrine config set up [1] doesn't work with my code base, or any code base I have tested with, maybe the docs are outdated. After ploughing through the Interwebs for hours, this is the configuration that finally made it work for me:

use Doctrine\ORM\Tools\Setup;
use Doctrine\ORM\EntityManager;
use Doctrine\Common\Annotations\AnnotationReader;

$paths = array( realpath(__DIR__."/../src/My/Entity") );
$isDevMode = TRUE;

// the connection configuration
$dbParams = array(
    'driver'   => 'pdo_mysql',
    'user'     => 'myuser',
    'password' => 's3cr3t',
    'dbname'   => 'mydb',
);

$cache = new \Doctrine\Common\Cache\ArrayCache();

$reader = new AnnotationReader();
$driver = new \Doctrine\ORM\Mapping\Driver\AnnotationDriver($reader, $paths);

$config = Setup::createAnnotationMetadataConfiguration($paths, $isDevMode);
$config->setMetadataCacheImpl( $cache );
$config->setQueryCacheImpl( $cache );
$config->setMetadataDriverImpl( $driver );

$entityManager = EntityManager::create($dbParams, $config);

//-- This I had to add to support the Mysql enum type.
$platform = $entityManager->getConnection()->getDatabasePlatform();
$platform->registerDoctrineTypeMapping('enum', 'string');
