Bean Validation with CDI2

Hi, we notice that, enabling Bean Validation in a project with jersey-cdi2-se, throws a NullPointerException during the boot process. After that, the validation works fine.

Steps to reproduce:
1) in the example project "jersey-cdi2-se" add the dependency
` `
` org.glassfish.jersey.ext`
` jersey-bean-validation`
` `
2) start the project
