Gson转换抛出类强制转换异常

Question

我正在使用下面的代码，

    String companyString= gson.toJson( "Here - List of objects converted to string" );
    List<SExecutive> sExecutiveList = gson.fromJson( companyString,
                                                                 new TypeToken<List>()
                                                                 {
                                                                 }.getType() );

上面的代码在运行时没有错误，它生成了sExecutiveList。但是当我在列表中使用对象时，它会抛出错误，

    java.lang.ClassCastException: java.lang.Object cannot be cast to com.deloitte.iq.data.beans.solr.SExecutive
