Update to Java 9

When it comes, let's add jaxb-api to the dependency. With gradle

compile group: 'javax.xml.bind', name: 'jaxb-api', version: '2.3.0'

With Maven

<dependency>
    <groupId>javax.xml.bind</groupId>
    <artifactId>jaxb-api</artifactId>
    <version>2.3.0</version>
</dependency>

The latest version at that time is recommended.

Reason

Starting with Java 9, [some J2EE classes are no longer visible from the JDK by default](https://docs.oracle.com/javase/9/migrate/toc.htm#JSMIG-GUID-F640FA9D-FB66-4D85 -AD2B-D931174C09A3) is the cause.

Java startup options can also be used, but considering the future, it is better to describe the dependency in the build system.
