What version of BeanIO are you using? What JDK version?

BeanIO 2.1.0
java version "1.8.0_11"
Java(TM) SE Runtime Environment (build 1.8.0_11-b12)


Please provide any additional information below.

This error occurs because 
org.beanio.internal.config.annotation.AnnotationParser doesn't set 
GroupConfig's order inside the method createGroup(TypeInfo info, Group group).

I've attached a test case and a patch for AnnotationParser.
