Equals method of Embeddable object not getting called.
------------------------------------------------------

         Key: HHH-2483
         URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-2483
     Project: Hibernate3
        Type: Bug

  Components: core  
    Versions: 3.2.2    
 Environment: Hibernate 3.2.2, JavaDB
    Reporter: Unnikrishnan.k.v


As a work around to issue reported in HHH-2482, I tried using a Embeddable object *PasswordHolder* which implements correct equals method to compare char[]'s.
But even then hibernate is calling equals method of char[] instead of equals method implemented in PasswordHolder.

I am pasting the PasswordHolder source below. To reproduce the issue, 
1. create an entity with PasswordHolder as embedded field.
2. Use version number for optimistic locking. 
3. Insert a row into db. 
4. Now fetch this row through Hibernate entity manager.
5. After the program exits, check the version number of the accessed row.  

import java.io.Serializable;
import java.sql.SQLClientInfoException;
import javax.persistence.Column;
import javax.persistence.Embeddable;

/**
 *
 * @author unni
 */
@Embeddable
public class PasswordHolder  implements Serializable {
    
    /** Creates a new instance of Password */
    public PasswordHolder() {
    }
    
    public PasswordHolder(char[] password) {
       this.password = password; 
    }
    
    
    private char[] password;

    @Column(length = 32, nullable = false)
    public char[] getPassword() {
        return password;
    }

    public void setPassword(char[] password) {
        this.password = password;
    }
    
    public boolean equals(Object o) {
        
        if (o instanceof PasswordHolder) {
            AppUtil appUtil = AppUtil.getInstance();
            return (0 == appUtil.compare(this.password, ((PasswordHolder)o).password));   
        }
        
        return false;
    }

    public int hashCode() {
        return password.hashCode();
    }
}
