[hibernate-dev] @org.hibernate.annotations.Index and NullPointerException in IndexOrUniqueKeySecondPass

[Laurent Almeras]

Hello,

I encounter a NullPointerException in IndexOrUniqueKeySecondPass with 
Hibernate 5.2.10.Final (stack at the end of mail).

It appears that problem seems to be linked to 
@org.hibernate.annotations.Index (deprecated annotation) used in an 
embeddable component, due to the following code that does not consider 
that Index can be declared in an embedded field 
(IndexOrUniqueKeySecondPass, l.75-76):

PersistentClass persistentClass = (PersistentClass) 
persistentClasses.get( column.getPropertyHolder().getEntityName() );
Property property = persistentClass.getProperty( column.getPropertyName() );

I don't know if you are willing to work on this issue as:

  * @org.hibernate.annotations.Index is deprecated for long
  * Using @Index on an embedded field can be considered as tricky

But this used to work in previous Hibernate version (last known working 
version: 5.1.2.Final)

On my side, replacing getPropertyHolder().getEntityName() by 
column.getPropertyHolder().getEntityOwnerClassName() fix my problem.

PersistentClass persistentClass = (PersistentClass) 
persistentClasses.get( 
column.getPropertyHolder().getEntityOwnerClassName() );
Property property = persistentClass.getProperty( column.getPropertyName() );

Please let me know if you want to work further on this problem so that I 
create an issue on Jira.
