Micronaut HTTP SSL Client bean fails

A declarative micronaut client

@Client("client1")
interface Client1 {
    @Get
    HttpResponse<String> test()
}

or a bean

ctx.getBean(RxHttpClient, Qualifiers.byName("client1"))

with following configuration:

micronaut:    
  ssl:
    enabled: true
  server:
    ssl:
      client-authentication: NEED
      key-store:
        path: classpath:test/certs/server.p12
        password: secret
      trust-store:
        path: classpath:test/certs/truststore
        password: secret
  http:
    services:
      client1:
        urls:
          - https://localhost:8443
        ssl:
          enabled: true
          client-authentication: NEED
          key-store:
            path: classpath:test/certs/client1.p12
            password: secret

Causes following error:

io.netty.handler.codec.DecoderException: javax.net.ssl.SSLHandshakeException: null cert chain
	at io.netty.handler.codec.ByteToMessageDecoder.callDecode(ByteToMessageDecoder.java:475)
	at io.netty.handler.codec.ByteToMessageDecoder.channelRead(ByteToMessageDecoder.java:283)

whereas a client instantiated

new DefaultHttpClient(embeddedServer.getURL(), ctx.getBean(HttpClientConfiguration, Qualifiers.byName("client1")))

works.
