Hello all,

It looks like Wildfly 10 changes a method interface in undertow and the keycloak is still linking against the old method.  Going across a redirect, I get this exception:

java.lang.NoSuchMethodError: io.undertow.server.Connectors.ungetRequestBytes(Lio/undertow/server/HttpServerExchange;[Lorg/xnio/Pooled;)V

org.keycloak.adapters.undertow.SavedRequest.tryRestoreRequest(SavedRequest.java:112)

org.keycloak.adapters.undertow.ServletSessionTokenStore.restoreRequest(ServletSessionTokenStore.java:119)

org.keycloak.adapters.undertow.ServletSessionTokenStore.isCached(ServletSessionTokenStore.java:67)

org.keycloak.adapters.undertow.ServletKeycloakAuthMech.authenticate(ServletKeycloakAuthMech.java:94)

Looking at this commit:

https://github.com/undertow-io/undertow/commit/b62c3f1efadeb86d94ed6577f59a8705e0ba8cb5#diff-5f4196395618b4f5f665d36a4f3773cd

the parameters changed type (from Pooled<ByteBuffer> to PooledByteBuffer).

This is called from here:

https://github.com/keycloak/keycloak/blob/master/integration/undertow/src/main/java/org/keycloak/adapters/undertow/SavedRequest.javahttps://github.com/keycloak/keycloak/blob/master/integration/undertow/src/main/java/org/keycloak/adapters/undertow/SavedRequest.java

I'm guessing the call on 112 needs to make the new object type?

Should I file a bug in the JIRA?

Thanks,

Kenn
