Server-spi UserCredentialModel mismatch

Hi,

I’m trialing out Keycloak so I took the latest version (9.0.0).
Using the quickstarts example https://github.com/keycloak/keycloak-quickstarts/blob/9.0.0/user-storage-simple/src/main/java/org/keycloak/quickstart/writeable/PropertyFileUserStorageProvider.java
the https://github.com/keycloak/keycloak/blob/9.0.0/server-spi/src/main/java/org/keycloak/models/UserCredentialModel.java doesn’t match the expected.

Also when starting Keycloak 9.0.0 I get:
Keycloak 9.0.0 (WildFly Core 10.0.3.Final) started in 25865ms
but from the pom you target <wildfly.version>18.0.1.Final</wildfly.version>

Did something when wrong with this latest release? Will you do a 9.0.1 corrective one soon?

Thanks,
LA

found:

/**
 * This method exists only because of the backwards compatibility. It is recommended to use {@link #getChallengeResponse()} instead
 */
public String getValue() {
    return getChallengeResponse();
}

but still don’t understand the mismatch in the Wildfly version.
