Description

If I simply uncomment the jarowinkler spellchecker in the Solr 4.0 example I get a nasty looking exception because the solrconfig.xml element for the distanceMeasure parameter has white space to format the XML nicely.

The exception:

SEVERE: Unable to create core: collection1
org.apache.solr.common.SolrException: Error loading class '

The Solr 4.0 example XML from solrconfig.xml:

    <!-- a spellchecker that uses a different distance measure -->
    <!--
       <lst name="spellchecker">
         <str name="name">jarowinkler</str>
         <str name="field">name</str>
         <str name="classname">solr.DirectSolrSpellChecker</str>
         <str name="distanceMeasure">
           org.apache.lucene.search.spell.JaroWinklerDistance
         </str>
       </lst>
     -->
