Exception in Doctrine's Cache Warmer results in blank Page in Production Environment

[stollr]

Hi.
I had the problem that I got a blank page when I loaded the application the first time after removing the cache directory (only on production environment). Nothing was shown or logged. Only the PHP error log said

PHP Fatal error:  Uncaught exception 'ReflectionException' with message 'Class integer does not exist' in C:\projects\osl\trunk\vendor\doctrine\lib\Doctrine\ORM\Proxy\ProxyFactory.php:226
Stack trace:

The problem was that there has been made a mistake in an entity (class \integer did not exist):

public function setAdrid(\integer $adrid)
{
    $this->adrid = $adrid;
    return $this;
}

It would be nice if this exception could be catched anywhere in Symfony and the error page could be loaded.

After I have run

php app\console cache:clear --env=prod --no-debug

This error does not appear anymore... don't know why.
