[keycloak-user] Stateful per-realm objects

[Dmitry Telegin]

Hi,

A new login protocol endpoint instance is created each time per-
request (o.k.protocol.LoginProtocolFactory::createProtocolEndpoint). I
need all the instances to have access to a shared, per-realm stateful
object.
(Background: I'm implementing OpenID 2.0 for Keycloak using openid4java
library. There, the central concept is ServerManager, a per-endpoint
singleton that stores cryptographic associations and other shared
data.)

Just wondering if there's already similar mechanism in Keycloak. It
shouldn't be that hard to implement a singleton registry, but it'd
prefer not to reinvent the wheel.

Thanks!
Dmitry
