JDK 11 Support

The JAXB modules which the Eureka server depends upon were removed in JDK 11. If you intend to use JDK 11 when running a Eureka server you must include these dependencies in your POM or Gradle file.

<dependency>
	<groupId>org.glassfish.jaxb</groupId>
	<artifactId>jaxb-runtime</artifactId>
</dependency>
