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,
