I've found a way to fix my problem... I just create a new session and start
a transaction for every API request to that endpoint:
this.session = KeycloakApplication.createSessionFactory().create();
this.session.getTransactionManager().begin();
At the end of the endpoint I commit and close this generated session.
This looks so wrong... now the endpoint is way slower and the log is full
of those warning due to using internal SPIs. Any clue about a better
alternative or how to fix my original problem? If this things happen when
programming SPIs and developers don't have a guideline about how to use
Keycloak's transaction model, it will make developers life harder.
Thanks.
