OIDC Client in Wildfly 26.0.1: Query parameters lost on redirection to Keycloak service

[Zeta]

When accessing a protected URL with query parameters in a secured Web application and a redirection for authentication is required, WildFly OIDC client ignores (or loses)  query parameters. So, they are not available when redirecting to the orginal URL after the user is authenticated.

For example, when accessing a secured URL with query parameters:

http://host/web-app/resource?param1=value1

WildFly OIDC client redirects to Keycloak service using the URL:

http://keycloak/realms/test/protocol/openid-connect/auth?

response_type=code

&client_id=web-app

&redirect_uri=http%3A%2F%2Fhost%3A8080%2Fweb-app%2Fresource

&state=7b326bd7-087e-4788-9ed9-2f1b781fdcad

&scope=openid

Is this not supported, a bug or a missed configuration?

Thanks in advance
