I recently upgraded from hibernate 3.2.6.ga to 3.3.1.ga and detected a problem related to javassist – the new default bytecode provider, and a specific domain/entity model. This happens when a setter method is overloaded and I am seeking your advice because I would like to know if this is just poor entity setup or is it really a bug in javassist that should be fixed.
The example is as follows:
Mapping:
Code:
<?xml version="1.0"?>
<!DOCTYPE hibernate-mapping PUBLIC "-//Hibernate/Hibernate Mapping DTD 3.0//EN"
"http://hibernate.sourceforge.net/hibernate-mapping-3.0.dtd">
<hibernate-mapping>

   <class name="com.audaxys.example.PostalCode" table="postal" proxy="com.audaxys.example.PostalCode" >
   <id name="gid" type="long">
            <column name="gid"/>
            <generator class="......." />
        </id>
      <version name="domainVersion" column="recversion" />
      <property name="code" type="string">      
         <column name="code"  not-null="true"  />
      </property>      
   </class>
   
</hibernate-mapping>


Then I have an abstract class with all the entity's setters and getters:
Code:
package com.audaxys.example;
...

public abstract class AbstractPostalCode {

   private Long gid;
   private String code;

   public AbstractPostalCode() {
   }

   public String getCode() {
      return code;
   }
   public void setCode(String code) {
      this.code = code;
   }
}


And then a concrete class where the setter is overloaded:
Code:
package com.audaxys.example;
...

public class PostalCode extends AbstractPostalCode {


   public PostalCode() {
      super();
   }

   public void setCode(Integer code) {
      setCode(code.toString());
   }
}


When I do a save in hibernate I get this exception:
Code:
org.springframework.orm.hibernate3.HibernateSystemException: IllegalArgumentException occurred while calling setter of com.audaxys.example.PostalCode.code; nested exception is org.hibernate.PropertyAccessException: IllegalArgumentException occurred while calling setter of com.audaxys.example.PostalCode.code
