> Key: SOLR-6271
> URL: https://issues.apache.org/jira/browse/SOLR-6271
> Project: Solr
> Issue Type: Bug
> Components: spellchecker
> Affects Versions: 4.9

>
> See ConjunctionSolrSpellChecker.java
> try {
> if (stringDistance == null) {
> stringDistance = checker.getStringDistance();
> } else if (stringDistance != checker.getStringDistance()) {
> throw new IllegalArgumentException(
> "All checkers need to use the same StringDistance.");
> }
> } catch (UnsupportedOperationException uoe) {
> // ignore
> }
> In line stringDistance != checker.getStringDistance() there is comparing by
> references. So if you are using 2 or more spellcheckers with same distance
> algorithm, exception will be thrown anyway.
