原因


IllegalArgumentException – if the cookie name is null or empty or contains any illegal characters (for example, a comma, space, or semicolon) or matches a token reserved for use by the cookie protocol

大致意思：

IllegalArgumentException – 如果 Cookie 名称为空或空，或包含任何非法字符（例如，逗号、空格或分号）或匹配保留供 Cookie 协议使用的令牌
