Unhelpful error message if observer message is annotated @Inject

WELD-000408 org.jboss.weld.event-ObserverMethod-com.foobar.MyPortableExtension.method afterDeploymentValidation(javax.enterprise.inject.spi.AfterDeploymentValidation, javax.enterprise.inject.spi.BeanManager) cannot be annotated with @Initializer

• Should say @Inject !
• Should say that observer methods are automatically injection points
