> To make org.hibernate.ejb.metamodel.AttributeFactory.PluralAttributeMetadataImpl.getClassFromGenericArgument(Type) works after migrating from 3.3.2.GA to 3.5.0-Final. I have to change the method whith:
> private Class<?> getClassFromGenericArgument(java.lang.reflect.Type type) {
> 	Class<?> javaType;
> 	Object unsafeElementType = type;
> 	if ( unsafeElementType instanceof Class ) {
> 		javaType = (Class) unsafeElementType;
> 	}
> 	else if ( unsafeElementType instanceof TypeVariable ) {
> 		final java.lang.reflect.Type upperBound = ( ( TypeVariable ) unsafeElementType ).getBounds()[0];
> 		javaType = getClassFromGenericArgument( upperBound );
> 	}
>         // ADDED TO FIX THE ParameterizedType
> 	else if ( unsafeElementType instanceof ParameterizedType) {
> 		javaType = (Class<?>)((ParameterizedType)type).getRawType();
> 	}
>         // END FIX
> 	else {
> 		throw new AssertionFailure("Fail to process type argument in a generic declaration. Type: "
> 				+ type.getClass() );
> 	}
> 	return javaType;
> }
> Is there an other way to manage the ParameterizedType?
