             Summary: NPE in Solr SpellCheckComponent if more than one QueryConverter
                 Key: SOLR-4304
                 URL: https://issues.apache.org/jira/browse/SOLR-4304
             Project: Solr
          Issue Type: Bug
          Components: spellchecker
    Affects Versions: 4.0
            Reporter: Jack Krupansky


The Solr SpellCheckComponent uses only a single QueryConverter, but fails with an NPE if more than one QueryConverter class is registered in solrconfig.xml.

Repro:

1. Add to 4.0 example solrconfig.xml:

<queryConverter name="myQueryConverter-1" class="solr.SpellingQueryConverter"/>
<queryConverter name="myQueryConverter-2" class="solr.SuggestQueryConverter"/>

2. Perform a spellcheck request:

curl "http://localhost:8983/solr/spell?q=test&indent=true"

3. Examine the NPE:

Suggested resolution: Use the first QueryConverter, but give a warning that indicates the class name of the one being used. Alternatively, throw a nasty but informative exception indicating the true nature of the problem.
