Description

The Stempel stemmer appears to be broken under Solr in v4.0.0-BETA, very likely related to LUCENE-2510 / LUCENE-4044.

When I add the following to the example, I get the below-listed exception on start-up:

solrconfig.xml

<lib dir="../../../contrib/analysis-extras/lucene-libs/" regex=".*\.jar"/>

schema.xml

<fields>
  <field name="content" type="text_pl" indexed="true" stored="false" multiValued="true"/>
[...]
<types>
  <fieldType name="text_pl" class="solr.TextField" positionIncrementGap="100">
    <analyzer>
      <tokenizer class="solr.StandardTokenizerFactory"/>
      <filter class="solr.LowerCaseFilterFactory"/>
      <filter class="solr.StempelPolishStemFilterFactory"/>
    </analyzer>
  </fieldType>

Solr console output
