Jetty-Connector No Client EndPointIdentificationAlgorithm

We're using KumuluzEE (3.1.0) as our server, which in turn uses Jetty (9.4.14) and Jersey (2.27).
When using the Jax-RS-Client to make a simple HEAD request like

`ClientBuilder.newClient().target('https://google.com').request().head();`

Jetty spills out the following warning:

> org.eclipse.jetty.util.ssl.SslContextFactory -- No Client EndPointIdentificationAlgorithm configured for SslContextFactory@5eccfb4b[provider=null,keyStore=null,trustStore=null]

Which it does, when the org.eclipse.jetty.util.ssl.SslContextFactory._endpointIdentificationAlgorithm is null.
The corresponding adapter code is in org.glassfish.jersey.jetty.connector.JettyConnector:

```
Boolean enableHostnameVerification = (Boolean) config.getProperties()
.get(JettyClientProperties.ENABLE_SSL_HOSTNAME_VERIFICATION);

if (enableHostnameVerification != null && enableHostnameVerification) {
sslContextFactory.setEndpointIdentificationAlgorithm("https");
}
```
So essentially if this setting is absent, it is treated as false. However the javadoc in org.glassfish.jersey.jetty.connector.JettyClientProperties state:

> If the property is absent the default value is {[at]code true}

Which kind of makes me feel, that the absent property case is not treated the right way.
