[jira] [Commented] (SOLR-11858) NPE in DirectSpellChecker

    [ https://issues.apache.org/jira/browse/SOLR-11858?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16347370#comment-16347370 ] 

Cassandra Targett commented on SOLR-11858:
------------------------------------------

I'm not able to reproduce this with either 7.1 or 7.2, but not sure if I'm following your setup. Here's what I did:

# Started Solr with {{bin/solr -e techproducts}}. This:
## Creates a collection with the {{sample_techproducts_config}} with spellcheck defaults that seem to match with what  you used
## Indexes exampledocs
# Then I did a query for "aple" to the /spell requestHandler: http://localhost:8654/solr/techproducts/spell?q=aple
# I got 1 result as expected for that dataset ("apple").

Can you correct these steps or add any additional information to try to reproduce this?

> We just came across the following NPE. It seems this NPE only appears when the query is incorrectly spelled but response has more than 0 results. We have not observed this on other 7.1.0 deployments.
