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:

Caused by: java.lang.NullPointerException
	at org.hibernate.cfg.annotations.CollectionBinder.buildOrderByClauseFromHql(CollectionBinder.java:851)

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{
