Keycloak 22 support

[rblaine95]

Hi there

I tried to add this provider to Keycloak 22 and it seems to cause Keycloak to crash during init.

Would it be possible to add support for Keycloak 22?

Docker compose to replicate:

version: "3.8"

  keycloak-init:

So hello @rblaine95. I just fixed the problem with the v22 of Keycloak. The problem is that they removed the support for v11 and thus the Kotlin wasn't working anymore without the required std. I had it added and now it's fixed.

Awesome @stephane-segning, thank you!
