suggester component from trunk throwing error

[abhayd]

hi 
I am trying to configure suggester component. I downloaded solr from trunk
and did a build.

here is my config
  <requestHandler name="/suggest"
class="org.apache.solr.handler.component.SearchHandler">
        <lst name="defaults">
                <str name="spellcheck">true</str>
                <str name="spellcheck.dictionary">suggest</str>
                <str name="spellcheck.count">10</str>
        </lst>
        <arr name="components">
         <str>suggest</str>
        </arr>
  </requestHandler>

  <searchComponent name="suggest" class="solr.SpellCheckComponent">
        <lst name="spellchecker">
                <str name="name">suggest</str>
                <str 
name="classname">org.apache.solr.spelling.suggest.Suggester</str>
                <str
name="lookupImpl">org.apache.solr.spelling.suggest.tst.TSTLookup</str>
                <str name="field">name_autocomplete</str>
                <str name="buildOnCommit">true</str>
        </lst>
  </searchComponent>

When i build my index, index gets created but i get following exception
