@AttributeOverride of column type or name results in PropertyNotFoundException
------------------------------------------------------------------------------

                 Key: HHH-2946
                 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-2946
             Project: Hibernate3
          Issue Type: Bug
         Environment: Hibernate 3.2.5.ga, Annotations 3.3.0.ga, Spring 2.0.7, MySQL 5.0.41-community-nt, Windows Vista
            Reporter: Juan Antonio Agudo

When trying to map a java.util.Map<String,String> hibernate by default creates VARCHAR(256) fields. When an attempt to alter for e.g. the column type to "TEXT" an Exception is thrown. For example:

@CollectionOfElements
@AttributeOverride(name="element.value", column=@Column(columnDefinition="TEXT"))
public Map<String, String> getSettings() {
      return settings;
}

results in 

Caused by: org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'sessionFactory' defined in file [C:\Users\tag\workspace\xyz\conf\applicationContext.xml]: Invocation of init method failed; nested exception is org.hibernate.PropertyNotFoundException: Could not find a setter for property bytes in class java.lang.String

This behaviour can be reproduced and was described fully in http://forum.hibernate.org/viewtopic.php?p=2368889#2368889

I attached an isolated sample code for review purposes.
