using DirectSpellChecker and FileBasedSpellChecker with Solr 4.10.1

[elisabeth benoit]

Hello,

I am using Solr 4.10.1 and trying to use DirectSolrSpellChecker and
FileBasedSpellchecker in same request.

I've applied change from patch 135.patch (cf Solr-6271). I've tried running
the command "patch -p1 -i 135.patch --dry-run" but it didn't work, maybe
because the patch was a fix to Solr 4.9, so I just replaced line in
ConjunctionSolrSpellChecker

else if (!stringDistance.equals(checker.getStringDistance())) {
         throw new IllegalArgumentException(
             "All checkers need to use the same StringDistance.");
       }


by

else if (!stringDistance.equals(checker.getStringDistance())) {
        throw new IllegalArgumentException(
            "All checkers need to use the same StringDistance!!! 1:" +
checker.getStringDistance() + " 2: " + stringDistance);
      }

as it was done in the patch

but still, when I send a spellcheck request, I get the error

msg": "All checkers need to use the same StringDistance!!!
1:org.apache.lucene.search.spell.LuceneLevenshteinDistance@15f57db32:
org.apache.lucene.search.spell.LuceneLevenshteinDistance@280f7e08"

>From error message I gather both spellchecker use same distanceMeasure
LuceneLevenshteinDistance, but they're not same instance of
LuceneLevenshteinDistance.

Is the condition all right? What should be done to fix this properly?

Thanks,
Elisabeth
