GRAILS-8805: Class reloading with table inheritance

Original Reporter: zorel
Environment: Not Specified
Version: 2.0.1
Migrated From: http://jira.grails.org/browse/GRAILS-8805

I encounter the following exception on my dev environment when I modify a domain using inheritance:

Message: Error creating bean with name 'org.grails.internal.SESSION_FACTORY_HOLDER': Cannot create inner bean '(inner bean)' of type [org.codehaus.groovy.grails.orm.hibernate.ConfigurableLocalSessionFactoryBean] while setting bean property 'sessionFactory'; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name '(inner bean)#2': Invocation of init method failed; nested exception is org.hibernate.DuplicateMappingException: Duplicate class/entity mapping test.ClassA

I wrote a simple test case to reproduce the error, it's quite simple: https://gist.github.com/1884458

The modification of rendered text in ClassA.pika() is sufficient to raise the exception.

I can confirm this bug: this worked with 1.3.7, but fails under 2.0.1.
