Tracked in https://github.com/keycloak/keycloak/issues/9871
Workaround for Infinispan 12.1.7.Final and tested until 14.0.19.Final to prevent a deadlock while
DefaultInfinispanConnectionProviderFactory is shutting down. Kept as a permanent solution and considered
good enough after a lot of analysis went into this difficult to reproduce problem.
See https://github.com/keycloak/keycloak/issues/9871 for the discussion.
