How to set SameSite LAX using JBOSS 7.4 - jboss

Question

We are currently using JBOSS 7.4 for functional testing. I've read on the documentation that undertow version is 2.2.5
and according to the undertow blog
that to configure the samesite cookie on a webapp, I have to added an undertow-handlers.conf file (located in the WEB-INF folder) which contains only the following line:
path(/)->samesite-cookie(mode=Lax)
but this is not working (I'll update with stacktrace later)
I tried different syntaxes but I still cannot start Jboss :
path(/)->samesite-cookie(mode=Lax, cookie-pattern=*) ---> PatternSyntaxException: Dangling meta character '*' near index 0
path(/)->samesite-cookie(mode="Lax", cookie-pattern="*") --->
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=\"*\")
^"}}
Any help will be greatly appreciated as none of the above is working.
Thank you.
