[jboss-jira] [JBoss JIRA] (WFLY-3297) Hibernate with enabled enhancer throws error at deployment

[Markus D (JIRA)]

     [ https://issues.jboss.org/browse/WFLY-3297?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Markus D updated WFLY-3297:
---------------------------

    Description: 
When I enable the enhancer in the persistence.xml then I receive an error from javassist at deployment.

https://community.jboss.org/message/871056#871056

public class TornadoStrikeSkill extends SelfTargetSkill {
	private static final long serialVersionUID = 1123460060768124078L;

	public TornadoStrikeSkill() {	}

	@Override
	protected void executeSkill() {
		.....
		GameObjectService gameObjectService = BeanLocator.lookup(GameObjectService.class);
                // getting the characters from an EJB
		for(GameCharacter victim : gameObjectService.calculateVictims()) {
			
		}
	}

public class GameCharacter extends GameObject {
	@OneToMany(mappedBy = "caster")
	private List<Skill> skills = new ArrayList<Skill>();

When I remove the for loop the error is gone. When I deploy the same application on JBoss 7.1 it works. So I guess the classloading has changed.

Maybe the cyclic dependency messes with the javassist?
