发现tomcat的一个bug

apache-tomcat-6.0.20-src

package org.apache.catalina.util;

public final class RequestUtil {

…

/**
* Decode and return the specified URL-encoded byte array. It is assumed
* the string is not a query string.
*
* @param bytes The url-encoded byte array
* @param enc The encoding to use; if null, the default encoding is used
* @exception IllegalArgumentException if a '%' character is not followed
* by a valid 2-digit hexadecimal number
*/
public static String URLDecode(byte[] bytes, String enc) {
return URLDecode(bytes, null, false);
} }

从函数声明看是要用enc对bytes进行解码，但实现时却没有用到enc这个参数。

已经提交并得到开发者确认了。
