Error while using external xml file (BluePrint) in l2switch stable/boron

I followed following steps to initialize l2switch module with reactive mode (i.e., making proactive mode false) with help of an external xml file as specified in blueprint doc at - https://wiki.opendaylight.org/view/Using_Blueprint#Using_the_Datastore

1. checkout l2switch origin/stable/boron branch and build project
2. cd l2switch/distribution/karaf/target/assembly/etc
3. mkdir -p opendaylight/datastore/initial/config/
4. gedit arp-handler-config_arp-handler-config.xml

<?xml version="1.0" encoding="UTF-8"?>

5. save file
6. start controller - distribution/karaf/target/assembly/bin/karaf debug
7. karaf log shows following read / parse error - http://pastebin.com/VAwnFaxq

8. I see the there are no flows installed on switches which implies reactive mode should be applied, but the error says otherwise (parsing the external xml file fails.)
