[keycloak-user] How to access entity manager from custom thread

[Libor Krzyžanek]

Hi,
it’s a jar in providers folder.

Does Keycloak 1.2 allows custom providers as a module?

Thanks,

If you created a module be sure to include 'javax.persistence.api' as a dependency. That was an issue I ran into, making sure I included the correct dependencies for my module.
