JBOSS 7.4配置SameSite=Lax失效报错如何解决

当前使用JBOSS 7.4进行功能测试，查阅Red Hat官方文档确认该版本内置的Undertow版本为2.2.5。根据Undertow官方博客的配置说明，为Web应用配置SameSite Cookie属性需要在WEB-INF目录下创建undertow-handlers.conf文件，文件中仅需写入如下配置行：
path(/)->samesite-cookie(mode=Lax)
实际配置后该规则并未生效（后续将补充对应的异常堆栈信息）。

先后测试了多种不同的配置语法，均无法正常启动JBoss，具体情况如下：

• 写入配置path(/)->samesite-cookie(mode=Lax, cookie-pattern=*)，启动时抛出异常：PatternSyntaxException: Dangling meta character '*' near index 0
• 写入配置path(/)->samesite-cookie(mode="Lax", cookie-pattern="*")，启动时抛出如下异常：

Caused by: java.lang.IllegalArgumentException: UT000045: Error parsing predicated handler string no handler named samesite-cookie known handlers are [disallowed-methods, allowed-methods, buffer-request, jdbc-access-log, http-continue-accept, secure-cookie, access-log, mark-secure, response-rate-limit, canonical-path, response-code, disable-cache, ssl-headers, trace, blocking, url-decoding, error-file, access-control, redirect, set, ip-access-control, request-limit, resource, compress, restart, clear, byte-range, eager-form-parser, done, rewrite, forwarded, stuck-thread-detector, reverse-proxy, jvm-route, learning-push, dump-request, proxy-peer-address, resolve-local-name, header, store-response, path-separator, resolve-peer-name]:
path(/)->samesite-cookie(mode="Lax", cookie-pattern="*")
                        ^

以上配置方式均无法正常生效，恳请得到相关帮助。
