[keycloak-user] Logout at security proxy fails

Hi, a few days ago I created the Jira issue KEYCLOAK-3311. Its about the following exception when "k_logout" request from the keycloak server is coming in: IllegalStateException: UT000126: Attempted to do blocking IO from the IO thread. This is prohibited as it may result in deadlocks Has anybody experienced the same? Is there a workaround? Currently this error prevents the logout from the secure proxy and therefore the protected application can still be reached (for a while) even if the user's session on the keycloak server has been terminated. Cheers, Manfred
