Am running in to this issue : https://issues.apache.org/jira/browse/SOLR-7606. But am not following all of the description there in that ticket.
But what I am not able to understand is when does a parent/child orthogonality is broken. And what does a child document without a parent mean ? I have a set of documents that have been added to solr (via an import from DB), And then in another process I fetch or recreate SolrInputDocument from DB those documents for which the relation need to be in place. And before adding them to Solr, I make sure all the parent and child documents are deleted from Solr and then I add this block of documents in to solr. And now when I query I get an ArrayIndexOutOfBoundException exactly as specified in that JIRA issue. Any insights on how and what should be done will be greatly appreciated.
