sauce-connect-plugin fails maven builds on JDK9

[vlukashov]

When trying to build a maven project that includes the sauce-connect-plugin on JDK9, the build fails with Execution start-sauceconnct of goal com.saucelabs.maven.plugin:sauce-connect-plugin:2.1.23:start-sauceconnect failed: A required class was missing while executing com.saucelabs.maven.plugin:sauce-connect-plugin:2.1.23:start-sauceconnect: javax/xml/bind/DatatypeConverter.

The same build passes just fine on JDK8.

$ java -version
java version "9.0.1"
Java(TM) SE Runtime Environment (build 9.0.1+11)
Java HotSpot(TM) 64-Bit Server VM (build 9.0.1+11, mixed mode)

$ mvn verify
...

The full source of the project is attached:
sauce-connect-plugin-jdk9.zip.

To reproduce the issue download and extract the source code, then run mvn verify inside it. The expected result is that the sauce connect plugin starts and complains that the
Sauce Labs username is not set:

SEVERE: Error retrieving Sauce Results

As a work-around you can add jaxb-api explicitly as a dependency for sauce-connect-plugin

<plugin>
    <groupId>com.saucelabs.maven.plugin</groupId>
    <artifactId>sauce-connect-plugin</artifactId>
.
.
.
    <dependencies>
        <dependency>
