Service creation for Hibernate Session results in ClassFormatError: Duplicate method name&signature

Hi, this report/question is for

tapestry-ioc 5.4.3
hibernate-core 5.2.10.Final
openjdk version "1.8.0_121"
OpenJDK Runtime Environment (build 1.8.0_121-8u121-b13-0ubuntu1.16.04.2-b13)
OpenJDK 64-Bit Server VM (build 25.121-b13, mixed mode)

I'm trying to have a ServiceId for a hibernate Session:

@ServiceId("HibernateSession")
public static Session buildHibernateSession(
    ObjectLocator objectLocator
) {
    return new Configuration()
        .configure("hibernate.cfg.xml")
        .buildSessionFactory()
        .openSession();
}

As soon as the HibernateSession is invoked by Tapestry-IOC, I get an
error:  java.lang.ClassFormatError: Duplicate method name&signature in
class file $Session_350f95bde0b5

Please note thate I can serve the SessionFactory perfectly fine with
Tapestry-IoC (just by omitting the "openSession()").

Is there something wrong in the code above?
Can someone reproduce it?
Is this a bug in Tapestry-IoC?
Is this a bug/limitation in Hibernate?
