Erro ao rodar Teste Unitario com Arquillian + JbossAs 6

Pessoal,

Estou tentando realizar os meus testes utilizando o arquillian do jboss.... porem ao tentar rodar ele. o eclipse me retorna o seguinte erro

alguem sabe como contornar isso ?

A configuração do meu pom.xml esta igual a da documentação do arquillian:
Inclusive eu ativei o profile no eclipse assim como informa a documentação..
