Erro ao tentar realizar teste usando JUnit + OpenEJB usando Java 8

Olá,

Estou tentando rodar um exemplo do site da apache:
https://github.com/apache/tomee/tree/042d4d9fc647c32ee31c4c7455a4769817564340/examples/simple-stateless

Porém fiz uma alteração por usar o java 8 atualizei o jar para o openejb 7.0.3, depois de colocar todas as dependencias obtive os dados abaixo na console:

Alguém conseguiria me dar uma luz?

Obrigado.
