Symfony issue 3691 serialization strings

symfony_3691_serialization_strings.txt

For reference, this are the serialized strings I get before messing with the implementation in AbstractToken:

PHP 5.4:
a:4:{i:0;O:37:"MyApp\Submodule\AppBundle\Entity\User":5:{s:41:"MyApp\Submodule\AppBundle\Entity\Userid";i:8;s:47:"MyApp\Submodule\AppBundle\Entity\Userusername";s:5:"admin";s:47:"MyApp\Submodule\AppBundle\Entity\Userpassword";s:88:"NZ7XOtPj4pkM6Klk9wLNrNuLYphlOhb40GXueK3b7Mh7EyiDND7fTyMM18DYz2tLDsLKsVl63L2uqe5CWb23Rg==";s:43:"MyApp\Submodule\AppBundle\Entity\Usersalt";s:32:"eaefd6e7b842c475a609a2f4f68fe12d";s:48:"MyApp\Submodule\AppBundle\Entity\UseruserRoles";O:33:"Doctrine\ORM\PersistentCollection":2:{s:39:"Doctrine\ORM\PersistentCollectioncoll";O:43:"Doctrine\Common\Collections\ArrayCollection":1:{s:54:"Doctrine\Common\Collections\ArrayCollection_elements";a:0:{}}s:46:"Doctrine\ORM\PersistentCollectioninitialized";b:0;}}i:1;b:1;i:2;a:1:{i:0;s:32:"eaefd6e7b842c475a609a2f4f68fe12d";}i:3;a:0:{}}

PHP 5.3:
a:4:{i:0;O:37:"MyApp\Submodule\AppBundle\Entity\User":5:{s:41:"MyApp\Submodule\AppBundle\Entity\Userid";i:8;s:47:"MyApp\Submodule\AppBundle\Entity\Userusername";s:5:"admin";s:47:"MyApp\Submodule\AppBundle\Entity\Userpassword";s:88:"NZ7XOtPj4pkM6Klk9wLNrNuLYphlOhb40GXueK3b7Mh7EyiDND7fTyMM18DYz2tLDsLKsVl63L2uqe5CWb23Rg==";s:43:"MyApp\Submodule\AppBundle\Entity\Usersalt";s:32:"eaefd6e7b842c475a609a2f4f68fe12d";s:48:"MyApp\Submodule\AppBundle\Entity\UseruserRoles";O:33:"Doctrine\ORM\PersistentCollection":2:{s:39:"Doctrine\ORM\PersistentCollectioncoll";O:43:"Doctrine\Common\Collections\ArrayCollection":1:{s:54:"Doctrine\Common\Collections\ArrayCollection_elements";a:0:{}}s:46:"Doctrine\ORM\PersistentCollectioninitialized";b:0;}}i:1;b:1;i:2;a:1:{i:0;O:37:"MyApp\Submodule\AppBundle\Entity\Role":3:{s:41:"MyApp\Submodule\AppBundle\Entity\Roleid";i:10;s:43:"MyApp\Submodule\AppBundle\Entity\Rolename";s:10:"ROLE_ADMIN";s:44:"MyApp\Submodule\AppBundle\Entity\Roleusers";O:33:"Doctrine\ORM\PersistentCollection":2:{s:39:"Doctrine\ORM\PersistentCollectioncoll";O:43:"Doctrine\Common\Collections\ArrayCollection":1:{s:54:"Doctrine\Common\Collections\ArrayCollection_elements";a:0:{}}s:46:"Doctrine\ORM\PersistentCollectioninitialized";b:0;}}}i:3;a:0:{}}

And afterwards with PHP 5.4:
a:4:{i:0;a:1:{i:0;O:37:"MyApp\Submodule\AppBundle\Entity\Role":3:{s:41:"MyApp\Submodule\AppBundle\Entity\Roleid";i:10;s:43:"MyApp\Submodule\AppBundle\Entity\Rolename";s:10:"ROLE_ADMIN";s:44:"MyApp\Submodule\AppBundle\Entity\Roleusers";O:33:"Doctrine\ORM\PersistentCollection":2:{s:39:"Doctrine\ORM\PersistentCollectioncoll";O:43:"Doctrine\Common\Collections\ArrayCollection":1:{s:54:"Doctrine\Common\Collections\ArrayCollection_elements";a:0:{}}s:46:"Doctrine\ORM\PersistentCollectioninitialized";b:0;}}}i:1;O:37:"MyApp\Submodule\AppBundle\Entity\User":5:{s:41:"MyApp\Submodule\AppBundle\Entity\Userid";i:8;s:47:"MyApp\Submodule\AppBundle\Entity\Userusername";s:5:"admin";s:47:"MyApp\Submodule\AppBundle\Entity\Userpassword";s:88:"NZ7XOtPj4pkM6Klk9wLNrNuLYphlOhb40GXueK3b7Mh7EyiDND7fTyMM18DYz2tLDsLKsVl63L2uqe5CWb23Rg==";s:43:"MyApp\Submodule\AppBundle\Entity\Usersalt";s:32:"eaefd6e7b842c475a609a2f4f68fe12d";s:48:"MyApp\Submodule\AppBundle\Entity\UseruserRoles";O:33:"Doctrine\ORM\PersistentCollection":2:{s:39:"Doctrine\ORM\PersistentCollectioncoll";O:43:"Doctrine\Common\Collections\ArrayCollection":1:{s:54:"Doctrine\Common\Collections\ArrayCollection_elements";a:1:{i:0;r:4;}}s:46:"Doctrine\ORM\PersistentCollectioninitialized";b:1;}}i:2;b:1;i:3;a:0:{}}
