Description

When fully qualified class name is used in schema.xml

org.apache.lucene.analysis.icu.ICUFoldingFilterFactory

it works. However as documented in confluence and wiki, when solr.ICUFoldingFilterFactory is used it throws following exception.

This is true for both released 4.8.1 version and trunk r1604168
following type works :

    
     <fieldType name="folded2" class="solr.TextField">
      <analyzer>
        <tokenizer class="solr.StandardTokenizerFactory"/>
        <filter class="org.apache.lucene.analysis.icu.ICUFoldingFilterFactory"/>
      </analyzer>
    </fieldType>

this does not :

 <fieldType name="folded" class="solr.TextField">
      <analyzer>
        <tokenizer class="solr.StandardTokenizerFactory"/>
        <filter class="solr.ICUFoldingFilterFactory"/>
      </analyzer>
    </fieldType>
