TYPO3.Flow

If any exception occurs while persisting, and a subsequent test also tries to persist, an ORM Exception occurs telling that the Entity manager were closed.
Reproduction code in Functional Test:

 1    /**
 2     * Fine, this throws, as expected, an Exception due to validation problems
 3     * 
 4     * @test
 5     * @expectedException \TYPO3\FLOW3\Persistence\Exception\ObjectValidationFailedException
 6     */
 7    public function firstFailingTestThatCorrectlyThrowsException() {
 8        $invalidAccount = new \TYPO3\FLOW3\Security\Account();
 9        $this->persistenceManager->add($invalidAccount);
10        $this->persistenceManager->persistAll();
11    }
12
13    /**
14     * This (same code) throws now "Doctrine\ORM\ORMException: The EntityManager is closed." 
15     * 
16     * @test
17     */
18    public function secondFailingTestThatSaysEntityManagerWasClosed() {
19        $invalidAccount = new \TYPO3\FLOW3\Security\Account();
20        $this->persistenceManager->add($invalidAccount);
21        $this->persistenceManager->persistAll();
22    }
