Renaming smooks xml configuration file extension can cause errors
-----------------------------------------------------------------

                 Key: JBIDE-7328
                 URL: https://jira.jboss.org/browse/JBIDE-7328
             Project: Tools (JBoss Tools)
          Issue Type: Bug
          Components: smooks
    Affects Versions: 3.2.0.Beta1
         Environment: JBDS 4.0.0.beta1 #47, Linux 64
            Reporter: Jiri Peterka
         Attachments: smooks-rename-exception.txt

Steps: 
1. Create project 
2. Create smooks configuration file 
3. Try to rename smooks configuration file and remove xml extension (you can try use .x or anything else than xml - it works as well) 

You'll see: An internal error occurred during:
