Jira issue originally created by user Alan Poulain:

Using a discriminator map and interfaces lead to an exception when there are not in alphabetical order.
For example,

/****
 * @ORM\DiscriminatorMap({
 *     "a" = "AEntityInterface",
 *     "b" = "BEntityInterface"
 * })
 */

is working but,

/****
 * @ORM\DiscriminatorMap({
 *     "b" = "BEntityInterface",
 *     "a" = "AEntityInterface"
 * })
 */

lead to:
{quote}
[Doctrine\Common\Persistence\Mapping\MappingException]
Class 'BEntityInterface' does not exist
{quote}

Could you double-check that there is no autoloading issue involved?

In particular, make sure you don't have both interfaces AEntityInterface and BEntityInterface in a file called AEntityInterface.php.
