In SolrJ, XMLResponseParser throws an exception when attempting to process a response with spellcheck.extendedResults=true containing word suggestions
------------------------------------------------------------------------------------------------------------------------------------------------------

                 Key: SOLR-1886
                 URL: https://issues.apache.org/jira/browse/SOLR-1886
             Project: Solr
          Issue Type: Bug
          Components: spellchecker
    Affects Versions: 1.4
            Reporter: Nicholas Brozack


This occurs when there are word suggestions.
The error occurs in the readArray method, the message being: "error reading value:LST"
The reason for this error is likely that the format of the response with the extendedResults option has unnamed lists.

Here is an example response where this occurs:
<response>

(response header is here)

<result name="response" numFound="0" start="0"/>
<lst name="spellcheck">
 <lst name="suggestions">
  <lst name="emaild">
	<int name="numFound">2</int>
	<int name="startOffset">0</int>
	<int name="endOffset">6</int>
	<int name="origFreq">0</int>
	<arr name="suggestion">
	 <lst>
	  <str name="word">email</str>
	  <int name="freq">2</int>
	 </lst>
	 <lst>
	  <str name="word">webmail</str>
	  <int name="freq">1</int>
	 </lst>
	</arr>
  </lst>
  <bool name="correctlySpelled">false</bool>
  <str name="collation">email</str>
 </lst>
</lst>
</response>

Surrounding the suggestions are unnamed lists.
Considering the method in XMLResponseParser is named readNamedList, I'm guessing that all lists must be named to avoid this error.
