Does Keycloak support elliptic curve TLS certs?

Configuring the server

Is it possible I’ve missed how to use EC keys for TLS for the keycloak server plse?

My private key file is:

-----BEGIN EC PARAMETERS-----
blahblah==
-----END EC PARAMETERS-----
-----BEGIN EC PRIVATE KEY-----
morebutlongerblah==
-----END EC PRIVATE KEY-----

And keycloak errors out with:

2022-06-27 12:48:26,835 ERROR [org.keycloak.quarkus.runtime.cli.ExecutionExceptionHandler] (main) ERROR: io.vertx.core.VertxException: java.lang.RuntimeException: Missing -----BEGIN PRIVATE KEY----- or -----BEGIN RSA PRIVATE KEY----- delimiter

FYI, replacing with RSA based certs it works fine, all running on java 17.02 which allegedly supports EC based algos.
