Failed to create Hibernate SessionFactory

Hello, I am experiencing this error when trying to create my EntityManager with Hibernate.

...INFO | 2016-07-28 14:55:20 | [main] internal.PooledConnections (PooledConnections.java:39) - HHH000115: Hibernate connection pool size: 20 (min=1) INFO | 2016-07-28 14:55:20 | [main] dialect.Dialect (Dialect.java:153) - HHH000400: Using dialect: org.hibernate.dialect.PostgreSQL95Dialect INFO | 2016-07-28 14:55:20 | [main] internal.LobCreatorBuilderImpl (LobCreatorBuilderImpl.java:124) - HHH000424: Disabling contextual LOB creation as createClob() method threw error : java.lang.reflect.InvocationTargetException INFO | 2016-07-28 14:55:20 | [main] type.BasicTypeRegistry (BasicTypeRegistry.java:148) - HHH000270: Type registration [java.util.UUID] overrides previous : org.hibernate.type.UUIDBinaryType@550a1967 Exception in thread "main" javax.persistence.PersistenceException: [PersistenceUnit: entityManager] Unable to build Hibernate SessionFactory at org.hibernate.jpa.boot.internal.EntityManagerFactoryBuilderImpl.persistenceException(EntityManagerFactoryBuilderImpl.java:961) at org.hibernate.jpa.boot.internal.EntityManagerFactoryBuilderImpl.build(EntityManagerFactoryBuilderImpl.java:891) at org.hibernate.jpa.HibernatePersistenceProvider.createEntityManagerFactory(HibernatePersistenceProvider.java:58)...

My persistence xml:
