Spring Data / JPA / Hibernate : Not committing changes - spring

Question

I'm trying to execute a query which has to delete items from a sub select.
Environment :
Wildfly 8.2
Spring Framework 4.1.6
Spring Data 1.8.0
Hibernate 4.3.10
MySQL 5
Here's the repository :
public interface MySecondEntityRepository extends JpaRepository<MySecondEntity, UUID> {
#Modifying
#Transactional(propagation = Propagation.REQUIRES_NEW)
#Query("DELETE FROM MySecondEntity e WHERE e.uuid IN ("
+ "SELECT e2.uuid "
+ "FROM MySecondEntity e2, MyEntity e1 "
+ "WHERE e2.entityUUID = e1.uuid "
+ "AND e1.uuid = :uuid "
+ "AND e1.*** = ..."
+ "AND e1.*** = ..."
+ ")")
public void deleteByEntityUUID(#Param("uuid") UUID entityUUID, ...);
}
Here's the transaction manager's XML definition :
<bean id="transactionManager" class="org.springframework.orm.jpa.JpaTransactionManager">
<property name="entityManagerFactory" ref="entityManagerFactory" />
</bean>
where entityManagerFactory is a LocalContainerEntityManagerFactoryBean.
I'm using them not to be dependent of the provider.
In the logs, I can see :
SQL | insert into HT_my_entity select ...
SQL | delete from my_entity where uuid IN (select uuid FROM HT_my_entity);
When I execute manually the select ..., I get the correct uuids to be deleted. but when spring/hibernate execute them, the transaction does not commit even with Propagation.REQUIRES_NEW. No exception thrown.

What I tried :
Propagation.REQUIRED and Propagation.REQUIRES_NEW
.flush() after the method's call
Unwrap the subquery to test it. It works correctly.
Update Spring Data / Hibernate
Note :
I do not include MySecondEntity in MyEntity for performance reason. A MyEntity can have 10k+ MySecondEntity. I know I can use lazy fetching but actually, entities are mapped to data transfert object and this cause issues to mapping process. Also, I do not want the retrieve all the data to delete them.
<tx:annotation-driven/> is defined
<aop:aspectj-autoproxy/> is defined
The method is called directly from a #RestController.
