Close session when client is closed

[mario-s]

Description

When I use the admin client in a Quarkus application, like in this tutorial and call the endpoint of the REST resource several times, the number of sessions increase with every request. This also happens when using the client in a try-with-resources block.

But the session is properly closed when executing tokenManager().logout();.

Note that there is already an issue in the Keycloak repository.

Discussion

No response

Motivation

Automatically cleanup every session when the close method of the client is used.

Details

I could provide a PR in the Keycloak repository for this issue. The change is small:

@Override
public void close() {
  if (this.tokenManager != null) {
    this.tokenManager.logout();
  }
  closed = true;
  client.close();
}
