This is mostly likely caused by incompatibility of Selenium server with Phantom JS, because you're using beta version.
So try upgrading it to the next stable, for example by the following lines in your pom.xml file:
<dependency>
<groupId>org.seleniumhq.selenium</groupId>
<artifactId>selenium-java</artifactId>
<version>3.5.2</version>
<scope>test</scope>
</dependency>
<dependency>
<groupId>org.seleniumhq.selenium</groupId>
<artifactId>selenium-chrome-driver</artifactId>
<version>3.5.2</version>
</dependency>
<dependency>
<groupId>com.codeborne</groupId>
<artifactId>phantomjsdriver</artifactId>
<version>1.3.0</version>
</dependency>
Then run mvn dependency:tree to build and display the dependency tree for this project.
