Chapter 6. Removed features

Both system properties have been used internally within Keycloak and have not been part of the official documentation. Red Hat build of Keycloak will fail to start if those are present.

Instead, use the command line option spi-cache-embedded-default-site-name as jboss.site.name replacement, and spi-cache-embedded-default-node-name as jboss.node.name replacement. See All provider configuration for more details on these options.

KeycloakSessionTask.useExistingSession was only useful to private server logic. Now that this logic has been refined, no need exists for this method.

In previous releases, there was a default implementation in the interface returning false and it is unlikely that it was overwritten in implementations.
