use of org.apache.lucene.analysis.util.StringMockResourceLoader in project lucene-solr by apache.

   * Ugly: but what to do? We want to test custom sort, which reads rules in as a resource.
   * These are largish files, and jvm-specific (as our documentation says, you should always
   * look out for jvm differences with collation).
   * So it's preferable to create this file on-the-fly.
