Describe the bug

If we haven't a default role configured, we get NullPointerException at [1] like:

ERROR [org.keycloak.services.error.KeycloakErrorHandler] (default task-3) Uncaught server error: java.lang.NullPointerException
at [[email protected]](mailto:[email protected])//org.keycloak.models.cache.infinispan.entities.CachedRealm.<init>(CachedRealm.java:266)
at [[email protected]](mailto:[email protected])//org.keycloak.models.cache.infinispan.RealmCacheSession.getRealm(RealmCacheSession.java:414)
(...)

Version

26.0.0

Regression

• The issue is a regression

Expected behavior

We need to prevent NullPointerException and log in [1] and log some information, like Realm name etc.

[1] https://github.com/keycloak/keycloak/blob/ef47eee2dda29a0f08187ae67970323c28947f11/model/infinispan/src/main/java/org/keycloak/models/cache/infinispan/entities/CachedRealm.java#L266###

Actual behavior

We get the following message when the default role is null:

ERROR [org.keycloak.services.error.KeycloakErrorHandler] (default task-3) Uncaught server error: java.lang.NullPointerException
at [[email protected]](mailto:[email protected])//org.keycloak.models.cache.infinispan.entities.CachedRealm.<init>(CachedRealm.java:266)
at [[email protected]](mailto:[email protected])//org.keycloak.models.cache.infinispan.RealmCacheSession.getRealm(RealmCacheSession.java:414)
(...)

How to Reproduce?

For example, remove the default role from the database.

Anything else?

Maybe we need to review the CachedRealm.java class and check for possible other points that could throw NPW
