Emmanuel Bernard resolved HIBERNATE-37.
---------------------------------------
Resolution: Duplicate Issue
Moved to http://opensource.atlassian.com/projects/hibernate/browse/HHH-1938
Problem in javassist instrumentation
------------------------------------
Key: HIBERNATE-37
URL: http://jira.jboss.com/jira/browse/HIBERNATE-37
Project: Hibernate
Issue Type: Bug
Environment: JBoss 4.0.4.GA
Hibernate 3.2 cr2
JDK 1.5 compiler
Reporter: Paolo Perrucci
Assigned To: Steve Ebersole
Given the following model:
public interface I
{
public Long getId();
public void setId(Long id);
public Number m1();
}
public class A implements I
{
private Long id;
public Long getId() { return id; }
public void setId(Long id) { this.id = id; }
public Integer m1() { return 0; }
}
<hibernate-mapping>
<class name="A" table="as" dynamic-update="true"
dynamic-insert="true">
<id name="id" type="java.lang.Long">
<generator class="native"/>
</id>
</class>
</hibernate-mapping>
When I deploy the har file to jboss I have the exceptions:

It seems that the problem is due to how the jdk 1.5 compiler create the class A.
Using javap you can see that A.class contains this two method:
public java.lang.Integer m1();
public java.lang.Number m1();
Actually the A.class contains the same method name twice.
