[keycloak-user] Admin Client for Java

Hello, I am using the Admin Client Java library to administer Keycloak resources (users,roles, groups, etc.) for a multi-tenant REST API running on Wildfly. I wonder what's the recommended usage of the library in this context, where multiple concurrent requests are the norm. Is it multi-threading safe? Should I use one instance for all tenants or maybe an instance per tenant? Cheers, Vagelis
