java反编译工具

Question

大家谁有好的反编译工具，推荐下，最近用那个jd-gui-0.3.3.windows，这个版本的工具出来之后总是一堆注释，很烦人，就这样的
/* / package baby.com.controllor.birthdayevent.formbean;
/ /
/ / import javax.servlet.http.HttpServletRequest;
/ / import org.apache.struts.action.ActionErrors;
/ / import org.apache.struts.action.ActionForm;
/ / import org.apache.struts.action.ActionMapping;
/ / import org.apache.struts.upload.FormFile;
/ */
用正则表达式替换，文件很多，很麻烦，所以向各位请教
