JMSSecuritybundle arrojando "security.expressions.expression" definido para la definición "security.expressions.expression

i recently configured JMSSecurityExtraBundle and when i try to add an expression to my firewall rules it throws me this error:

Fatal error: Uncaught exception 'Symfony\Component\DependencyInjection\Exception\RuntimeException' with message 'The parent definition "security.expressions.expression" defined for definition "security.expressions.expression.3b9a3b9db79b52922a36b870bc46e5b114425575" does not exist.'

I followed the exact description as described on this page:

http://jmsyst.com/bundles/JMSSecurityExtraBundle/master/installation

This is when the error occurs:

security:
    access_control:
        - { path: ^/foo, access: "hasRole('FOO') and hasRole('BAR')" }
