Description

The following exception is thrown when attempting to start up tapestry with the latest stable version of Hibernate (5.0.6.Final):

java.lang.NoSuchMethodError: org.hibernate.cfg.Configuration.getClassMappings()Ljava/util/Iterator;
	at org.apache.tapestry5.hibernate.modules.HibernateModule.contributeValueEncoderSource(HibernateModule.java:95) ~[tapestry-hibernate-5.4.0.jar:na]
	at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) ~[na:1.8.0_60]
	at sun.reflect.NativeMethodAccessorImpl.invoke(Unknown Source) ~[na:1.8.0_60]

	at org.apache.tapestry5.ioc.internal.ContributionDefImpl.invokeMethod(ContributionDefImpl.java:125) ~[tapestry-ioc-5.4.0.jar:na]

That is due to the fact that getClassMappings() was removed from org.hibernate.cfg.Configuration in Hibernate 5.

Luckily, it isn't really needed, and there is a backwards compatible way to do without it. I.e., tapestry can easily become compatible with Hibernate 5 without breaking compatibility with Hibernate 3 and 4.

I'll create a pull request on GitHub and link to it here.
