Actualicé Spring Boot a 1.4.2 e Hibernate a 5.0.11.Final y comencé a ver este error. No estoy seguro de por quéHibernateJpaAutoConfiguration está registrando el convertidor del cliente varias veces aunque se declare solo una vez.

La siguiente excepción se produce cuando intento ejecutarbootRun.

Cualquier ayuda sería realmente apreciable.
