Reordering of nodes in console throws exception in logs

I start the project with -Dhippoecm.export.dir=/home/jsheriff/projects/gogreen/trunk/content/src/main/resources/

1. Log-in to console using admin user-id
2. Navigate to /content/documents/hippogogreen/news/2009
3. Reorder the Folders you see

Actual Issue - While doing so I see below exceptions

4. On CMS front end - I can see the folders are reordered in "/content/documents/hippogogreen/news/2009" and Arabic is visible as a language
