[keycloak-user] Is Keycloak client admin thread safe?

It's supposed to be and we even internally using it in some concurrency 

It's using Apache HTTP client under the hood, which itself is 
thread-safe and is using connection pooling. In case you need, you can 
configure more fine-grained details (like connection pool size etc) by 
pass the custom resteasyClient to Keycloak object.

However when I looked a bit more into sources now, I can see that there 
are some potential concurrency issues in TokenManager class, which is 
used internally by admin client. Created JIRA 
https://issues.jboss.org/browse/KEYCLOAK-2731 for it. It's not too bad 
IMO, but note that you can possibly see situation when more concurrent 
threads are trying to refresh the same access token at the same time.
