code: private static String removeQuotes( String classpath ) {
      if( classpath.startsWith( "\"" ) )
      {
        classpath = classpath.substring( 1 );
      }
      if( classpath.endsWith( "\"" ) )
      {
        classpath = classpath.substring( 0, classpath.length()-1 );
      }
      return classpath;
    }
