title: ClassNotFoundException when applying Japanese filedType
body: <p>I downloaded Solr version 4.7.0, and then add a filter for Japanese file type like this (using example directory in package):</p>
  
  <pre><code>&lt;fieldType name="text_ja_start_with" class="solr.TextField" positionIncrementGap="100"&gt;
    &lt;analyzer type="index"&gt;
      &lt;tokenizer class="solr.JapaneseTokenizerFactory" mode="search" userDictionary="lang/userdict_ja.txt"/&gt;
      &lt;filter class="solr.JapanesePartOfSpeechStopFilterFactory" tags="lang/stoptags_ja.txt" /&gt;
      &lt;filter class="solr.StopFilterFactory" ignoreCase="true" words="lang/stopwords_ja.txt" /&gt;
      &lt;filter class="solr.CJKWidthFilterFactory"/&gt;
      &lt;filter class="solr.JapaneseKatakanaStemFilterFactory" minimumLength="4"/&gt;
      &lt;filter class="solr.JapaneseReadingFormFilterFactory" useRomaji="false"/&gt;
      &lt;filter class="solr.ICUTransformFilterFactory" id="Katakana-Hiragana"/&gt;
      &lt;filter class="solr.LowerCaseFilterFactory"/&gt;
      &lt;filter class="solr.EdgeNGramFilterFactory" minGramSize="1" maxGramSize="25" side="front"/&gt;
    &lt;/analyzer&gt;
    &lt;analyzer type="query"&gt;
      &lt;tokenizer class="solr.JapaneseTokenizerFactory" mode="search" userDictionary="lang/userdict_ja.txt"/&gt;
      &lt;filter class="solr.JapanesePartOfSpeechStopFilterFactory" tags="lang/stoptags_ja.txt" /&gt;

      &lt;filter class="solr.JapaneseReadingFormFilterFactory" useRomaji="false"/&gt;
      &lt;filter class="solr.ICUTransformFilterFactory" id="Katakana-Hiragana"/&gt;
      &lt;filter class="solr.LowerCaseFilterFactory"/&gt;

  <p>The server cannot start because of this error:</p>
  
  <blockquote>
    <p>Caused by: java.lang.ClassNotFoundException: org.apache.lucene.analysis.util.MultiTermAwareComponent</p>
  </blockquote>
  
  <p>I've done some searching but it's said that MultiTermAwareComponent is an abstract component of Solr ( <a href="http://lucene.apache.org/core/4_0_0/analyzers-common/org/apache/lucene/analysis/util/MultiTermAwareComponent.html" rel="nofollow noreferrer">http://lucene.apache.org/core/4_0_0/analyzers-common/org/apache/lucene/analysis/util/MultiTermAwareComponent.html</a>).
  So I don't know how to fix this.</p>
  
  <p>Update:</p>
  
  <p>I've found the cause make this error, when I copy 2 libs file (<strong>$root/contrib/analysis-extras/lucene-libs/lucene-analyzers-icu-4.7.0.jar</strong> and <strong>$root/contrib/analysis-extras/lib/icu4j-52.1.jar</strong>) for <strong>ICUTransformFilterFactory</strong> filter to $root/example/lib/ext, It throw the error above.When not add 2 file to libs directory, the error not happen but cannot use <strong>ICUTransformFilterFactory</strong> filter</p>
