I am getting the Exception

FAILED CONFIGURATION: @BeforeSuite arquillianBeforeSuite

Running Arquillian Tests in Eclipse Oxygen with TestNG and wildfly11. My Maven configuration is as follows:

    <dependency>
        <groupId>org.jboss.arquillian.testng</groupId>
        <artifactId>arquillian-testng-container</artifactId>
        <version>1.1.13.Final</version>
        <scope>test</scope>
    </dependency>
    <dependency>
        <groupId>org.testng</groupId>
        <artifactId>testng</artifactId>
        <version>6.11</version>
    </dependency>
    <dependency>
        <groupId>org.wildfly.arquillian</groupId>
        <artifactId>wildfly-arquillian-container-managed</artifactId>
        <version>2.0.1.Final</version>
        <scope>test</scope>
    </dependency>

The Solution was:

remove the the Wildfly 11 Runtime from the Classpath.

1. Right Click on the Project
2. Build Path
3. Configure Build Path
4. Libraries (Tab)
5. remove Wildfly 11 Runtime (or Wildfly 10 Runtime)

Why is this necessary? Comments welcome...
