Noble Paul updated SOLR-7508:
-----------------------------
Priority: Trivial (was: Major)
> SolrParams.toMultiMap() does not handle arrays
> ----------------------------------------------
>
> Key: SOLR-7508
> URL: https://issues.apache.org/jira/browse/SOLR-7508
> Project: Solr
> Issue Type: Bug
> Components: SolrJ
> Affects Versions: 5.0, 5.1
> Reporter: Thomas Scheffler
> Priority: Trivial
> Labels: easyfix, easytest
> Attachments: SOLRJ-7508.patch
>
>
> Following JUnit test to show what I mean:
> {code}
> ModifiableSolrParams params = new ModifiableSolrParams();
> String[] paramValues = new String[] { "title:junit", "author:john" };
> String paramName = "fq";
> params.add(paramName, paramValues);
> NamedList<Object> namedList = params.toNamedList();
> assertEquals("parameter values are not equal", paramValues,
> namedList.get(paramName));
> Map<String, String[]> multiMap = SolrParams.toMultiMap(namedList);
> assertEquals("Expected " + paramValues.length + " values",
> paramValues.length, multiMap.get(paramName).length);
> {code}
> The first {{assertEquals()}} will run fine, while the last one triggers the
> error. Suddenly the length of the array is "1" and it's value of {{fq}} is
> like {{[Ljava.lang.String;@6f09c9c0}}. Looking into the code I see that the
> toMultiMap() method does not even look for arrays.
