Build fails with Kotlin coroutine/suspend methods

Describe the bug

With latest release the build fails with this error message:

Build step io.quarkus.resteasy.reactive.server.deployment.ResteasyReactiveProcessor#setupEndpoints threw an exception: java.lang.RuntimeException: java.lang.RuntimeException: Failed to process method 'io.outfoxx.cloud.api.admin.server.AdminAPI#createAccount'

and the final cause error message is:

Resource method java.lang.Object createAccount(java.lang.String tenantId, io.outfoxx.cloud.api.CreateAccountParams body, javax.ws.rs.core.UriInfo uriInfo, kotlin.coroutines.Continuation<? super javax.ws.rs.core.Response> $completion) can only have a single body parameter: $completion

Notice the complaint about the $completion parameter in the method.

The suspend method is defined in an interface with the following signature:

@Path(value = "/admin/api/v1.0")
@Produces(value = ["application/json","application/cbor"])
@Consumes(value = ["application/json"])
interface AdminAPI
  
  //...

  @POST
  @Path(value = "/tenants/{tenantId}/accounts")
  public suspend fun createAccount(
    @PathParam(value = "tenantId") tenantId: String,
    @Valid body: CreateAccountParams,
    @Context uriInfo: UriInfo
  ): Response

  //...

}

An implementation class then derives from the interface and implements the methods. It builds fine in 2.13.0.Final

Expected behavior

Kotlin suspend methods work as they did in previous releases.

Actual behavior

Kotlin suspend methods in interfaces fails the

Yep it was the clean that was needed. For posterity here is my reproducer that generates the same error.
