I am trying to configure Helidon Webserver with mutual SSL in http4k.

The following is my configuration

class HelidonSsl(val port: Int = 8305) : ServerConfig {
override val stopMode = ServerConfig.StopMode.Immediate

override fun toServer(http: HttpHandler): Http4kServer {
    val keystorePath = "keystore/ssl.keystore"
    val keystorePassword = "changeit"

    // Set up SSL/TLS configuration if keystore and truststore are present
    val keyStoreKey = Keys.builder()
        .keystore(
            KeystoreKeys.builder()
                .keystore(Resource.create(keystorePath))
                .passphrase(keystorePassword)
                .trustStore(true)
                .build()
        )
        .build()

    val tlsConfig = TlsConfig.builder()
        .trustAll(true)
        .privateKey(keyStoreKey)
        .clientAuth(TlsClientAuth.OPTIONAL)
        .build()

    val server = WebServer.builder()
        .tls(tlsConfig)
        .port(port)
        .build()

    return object : Http4kServer {
        override fun start() = apply { server.start() }
        override fun stop() = apply { server.stop() }
        override fun port(): Int = if (port != 0) port else server.port()
    }
}

The server starts, but when connections are made, I get the following error stack :

I have checked :

• keystore – contains self signed cert usign RSA & password is fine – used the same keystore with Jetty and works fine
• different configuration options
• debugging shows that the key manager is set to DummyKeyManager instance and this seems to cause the errors but not sure how to fix that
