[hibernate-issues] [Hibernate-JIRA] Created: (ANN-617) NullPointerException when handling @OrderBy
NullPointerException when handling @OrderBy
-------------------------------------------
Key: ANN-617
URL: http://opensource.atlassian.com/projects/hibernate/browse/ANN-617
Project: Hibernate Annotations
Issue Type: Bug
Components: binder
Affects Versions: 3.3.0.ga
Environment: Hibernate Core 3.2.4.SP1; Hibernate Annotations 3.3.0 GA; Hibernate
EntityManager 3.3.1 GA; Oracle OC4J; Oracle DB 10g
Reporter: Jifeng Liu
After I updated from Hibernate Annotations 3.2.1ga to 3.3.0ga, I get the following
NullPointerException:

After I debug it, the variable 'pc' is null in the CollectionBinder.java:851
line:
table = pc.getTable().getQuotedName() + ".";
It seems like this bug is introduced by fix of ANN-516 '@OrderBy added to wrong table
in inheritance relationship'.
The related persist classes are:
// ------ The class with @OrderBy annotation
@Entity
@Table(name="RG_SECTION")
@IdClass(SectionID.class)
public class Section extends AbstractSection{
@ManyToMany(fetch=FetchType.EAGER)
@JoinTable(name="V_Current_Section_Term",
joinColumns= {
@JoinColumn(name="Section_School_Id",
referencedColumnName="School_Id"),
@JoinColumn(name="Section_ID",
referencedColumnName="Section_ID")},
inverseJoinColumns= {
@JoinColumn(name="Term_School_Id",
referencedColumnName="School_Id"),
@JoinColumn(name="Term_Academic_Yr",
referencedColumnName="Academic_Yr"),
@JoinColumn(name="Term_Sort_No",referencedColumnName="Term_Sort_No")}
)
@OrderBy("termSortNo")
public List<Term> getTerms() {
return super.getTerms();
}
// -------------- This Entity class in the Collection ---------
@Entity
@Table(name="SCHOOL_TERMS")
@IdClass(TermID.class)
public class Term extends AbstractBusinessObject implements Comparable{
