AssertionFailure thrown when collection contains a parameterized type
---------------------------------------------------------------------

                 Key: HHH-5098
                 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-5098
             Project: Hibernate Core
          Issue Type: Bug
          Components: entity-manager
    Affects Versions: 3.5.0-Final
            Reporter: Kahli Burke
         Attachments: patch.txt

The following exception is thrown when an entity exists with a collection containing a parameterized type:

ERROR [AssertionFailure] an assertion failure occured (this may indicate a bug in Hibernate): org.hibernate.annotations.common.AssertionFailure: Fail to process type argument in a generic declaration. Type: class sun.reflect.generics.reflectiveObjects.ParameterizedTypeImpl

	at org.jboss.jpa.deployment.PersistenceUnitDeployment.start(PersistenceUnitDeployment.java:316)

For example if a field exists like:
@OneToMany
List<SomeEntity<SomeClass>> associatedList;

I've attached a patch that includes a test case for the entity-manager project and a proposed fix.
