Keycloak Admin REST Client in OSGI enviroment

Hi,
I need to use Keycloak admin client to perform some operation to users community from an app secured by keycloak server.
This app run on OSGi enviroment (karaf).
Mandatory for Keycloak admin client is Resteasy, but it is not OSGi compliant.
Any suggestion to make it works?
Thanks for help.

Admin REST API request (I guess you want to use /{realm}/users*) is just HTTP call, so any http client compliant with your environment can do that.

Yes i know.
If it possible, i prefer to use official java client (https://www.keycloak.org/docs/latest/server_development/index.html#example-using-java). In case this will be impossible i should write a custom REST client to do same things.
