Issue Type:	Bug
Affects Versions:	5.0.8, 5.1.0
Assignee:	Unassigned
Attachments:	BytecodeEnhancementWithBatchFetching.zip
Components:	hibernate-core
Created:	03/Mar/2016 12:38 PM

Reporter:	Rodrigo Augusto de Moraes Lourenço

Batch Fetching stops working when I enable bytecode enhancement.

I'm using hibernate-enhance-maven-plugin for build time enhancement.

I used reflection at the Test case, is there a better way to validate this issue?

 
                                                                @Entity
public class Team {
	@Id
	@GeneratedValue(strategy = GenerationType.AUTO)
	private Integer id;
	
	@OneToMany(mappedBy="team")
	private List<Member> members;
 
                                                            

 
                                                                @Entity
public class Member {
	@Id
	@GeneratedValue(strategy = GenerationType.AUTO)
	private Integer id;
	
	private String name;
	
	@ManyToOne
	@JoinColumn(name="team_id")
	private Team team;
 
                                                            

persistence.xml

 
                                                                	<property name="hibernate.batch_fetch_style" value="DYNAMIC" />
	<property name="hibernate.default_batch_fetch_size" value="100" />

Bytecode Enabled, n+1 problem loading members

Hibernate:
/*
from
Team */ select
team0_.id as id1_1_
from
Team team0_
Hibernate:
/* load one-to-many com.test.entities.Team.members */ select
members0_.team_id as team_id3_0_1_,
members0_.id as id1_0_1_,
members0_.id as id1_0_0_,
members0_.name as name2_0_0_,
members0_.team_id as team_id3_0_0_
from
Member members0_
where
members0_.team_id=?

Bytecode Disabled, Batch Fetching working properly
