Sporadic ArrayIndexOutOfBoundsException on first few calls

    XMLWordPrintable

    Details

    • Steps to Reproduce:
      • Start keycloak server
      • run concurrent logins via oauth immediately
      • ERROR happens sporadic

      Description

      From time to time we get a sporadic failure when trying to login to keycloak 12.0.1 (on wildfly 21?!) via Oauth during test runs. This seems to happen on concurrent calls to the auth service:
