Getting Warning as NoSuchAlgorithmException in vert.x

I have implemented a backend call protected via bearer authentication to the Keycloak's userinfo endpoint using access token in vert.x framework. I am able to run this code without any errors. But I am getting this warning:

> May 16, 2022 10:33:04 AM
io.vertx.ext.auth.oauth2.impl.OAuth2AuthProviderImpl WARNING: Skipped
> unsupported JWK: java.security.NoSuchAlgorithmException: RSA-OAEP

Below is the code:

> OAuth2ClientOptions clientOptions = new OAuth2ClientOptions()
>                 .setFlow(OAuth2FlowType.AUTH_CODE)
>                 .setSite(System.getProperty("oauth2.issuer", "http://localhost:8080/auth/realms/myrealm"))
>                 .setClientID(System.getProperty("oauth2.client_id", "myclientid"))
>                 .setClientSecret(System.getProperty("oauth2.client_secret",
> "myclientscret"));
> 
> private Handler<RoutingContext> UserInfo(WebClient webClient, String
> userInfoUrl) {
> 
>         return (RoutingContext ctx) -> {

>             OAuth2TokenImpl user = (OAuth2TokenImpl) ctx.user();
> 
>             URI userInfoEndpointUri = URI.create(userInfoUrl);
>             webClient
>                     .get(userInfoEndpointUri.getPort(), userInfoEndpointUri.getHost(), userInfoEndpointUri.getPath())
>                     .bearerTokenAuthentication(user.opaqueAccessToken())
>                     .as(BodyCodec.jsonObject())
>                     .send(ar -> {
>                         JsonObject body = ar.result().body();
>                         respondWithOk(ctx, "application/json", body.encodePrettily());
>                     });
>         };
>     }

As this now throws a RuntimeException you might want to disable the key provider:

  • open Keycloak Admin, select the Realm used
  • go to Realm settings > Keys > Providers
  • click on rsa-enc-generated: switch enabled and active to off

In one instance, rsa-enc-generated was already set to disabled/deactivated. When I set it on and off again and hit the save button, the provider is actually disabled and the error disappears. But in a later instance it was correctly shown as enabled/active and I had to disable it to fix the error.

You can ignore this warning, it is just a warning on purpose.
