After a bloody fight, two beers and an amazing goal of the New Zealand
in the extra time, I fixed the damn problem.. (not a problem actually
just flickering perception caused by prolonged exposition to a
monitor.. )

I found the dependency required to have the JPA EnumType.class in the classpath:

        <dependency>
            <groupId>javax.persistence</groupId>
            <artifactId>persistence-api</artifactId>
            <version>1.0</version>
            <scope>test</scope>
        </dependency>

works like a charm now..

Once more, thanks to the tip of Sandoz ... :)
