[hibernate-issues] [Hibernate-JIRA] Commented: (HSEARCH-526) Mass Indexer Logs Multiple NullPointerExceptions

[j nadler (JIRA)]

    [ http://opensource.atlassian.com/projects/hibernate/browse/HSEARCH-526?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=37039#action_37039 ] 

j nadler commented on HSEARCH-526:
----------------------------------

Sanne,

I have @Indexed class Parent, @Indexed class Child1 extends Parent, @Indexed class  Child2 extends Parent, unindexed class Child3 extends Parent.

I create an indexer fullTextEntityManager.createIndexer(Parent.class), it seems that it then fetches all Parent entities.  This includes all Child3 entities but Child3 is not indexed.  It seems like the MassIndexer attempts to index them anyway.

Best behavior might be to ignore these (explicitly check if the concrete subtype is @Indexed, skip that record if not, possibly log a warning) or as you say it could at least throw an error that makes it clear what the developer (me) did wrong.

Thanks!

Jeff

> We just moved our 'old style' reindex code to the new MassIndexer and gave it a run.  It seems to have mostly worked (the index was clearly populated with some records) but a few NPEs in the logs:
