I have the exactly same problem here. I identified this error when my subclass
extends other with generics, restricting the parameters.
Example:
-------------------------------------------------------------------
| PersistentObject.java
|
| public interface PersistentObject<U, V> extends java.io.Serializable {
| public U getOid();
| public void setOid(U oid);
| public V getVersion();
| public void setVersion(V version);
| }
| -------------------------------------------------------------------
| BasePersistentObjectImpl.java
|
| public abstract class BasePersistentObjectImpl<OID, VERSION> implements
PersistentObject<OID, VERSION> {
| protected OID oid;
| protected VERSION version;
| public void setOid(OID oid) {
| this.oid = oid;
| }
| public void setVersion(VERSION version) {
| this.version = version;
| }
| }
| ---------------------------------------------------------------
| OIDPersistentObjectImpl.java
|
| import javax.persistence.*;
|
| @MappedSuperclass
| public abstract class OIDPersistentObjectImpl<OID extends CharSequence,
VERSION> extends BasePersistentObjectImpl<OID, VERSION> {
| @Id
| @GeneratedValue
| public OID getOid() {
| return oid;
| }
| @Version
| public VERSION getVersion() {
| return version;
| }
| }
| -------------------------------------------------------------------
| PersonVo.java
|
| public interface PersonVo extends PersistentObject<String, Integer> {
| public String getName();
| public void setName(String name);
| }
| -------------------------------------------------------------------
| PersonVoImpl.java
|
| import javax.persistence.Entity;
|
| @Entity
| public class PersonVoImpl extends OIDPersistentObjectImpl<String, Integer>
implements PersonVo {
| private String name;
| public String getName() {
| return this.name;
| }
| public void setName(String name) {
| this.name = name;
| }
| }
| -------------------------------------------------------------------
This example gives the following error:
12:15:40,372 ERROR [BasicLazyInitializer] Javassist Enhancement failed:

If I remove the "extends CharSequence" from the OID generic parameter in class
OIDPersistentObjectImpl.java, the example works perfectly.
This error began to happen in the jboss4.0.4.ga, with Hibernate Annotations and
Entitymanager 3.2.0 CR1. With Annotaions and Entitymanager 3.1 beta this error
doesnt happen.
Probably a new "bugfeature" of the new version of Hibernate??
