Possible error in tapestry-beanvalidator?

Before i begin, a warning. I am not yet an experienced tapestry user. But
5.3.7 is great and works very well for my application!

I have decided to give 5.4 a try. I simply changed my pom.xml to use
5.4-22beta. After making a couple other changes in the pom, and my
hibernate cfg, I run mvn jetty:run-war. I am doing this from inside
intellij idea

This is the only error i get:

java.lang.RuntimeException: Service id 'ValidatorFactory' has already been
defined by
org.apache.tapestry5.beanvalidator.BeanValidatorModule.buildValidatorFactory(BeanValidatorSource,
PropertyShadowBuilder) (at BeanValidatorModule.java:67) and may not be
redefined by
org.apache.tapestry5.beanvalidator.modules.BeanValidatorModule.buildValidatorFactory(BeanValidatorSource,
PropertyShadowBuilder) (at BeanValidatorModule.java:70). You should rename
one of the service builder methods.

Any ideas?
