NullPointerException in Foreach.java - PatchAvailable
-----------------------------------------------------

                 Key: VELOCITY-759
                 URL: https://issues.apache.org/jira/browse/VELOCITY-759
             Project: Velocity
          Issue Type: Bug
          Components: Engine
            Reporter: Rachid
            Priority: Trivial


I checked out the code from http://svn.apache.org/repos/asf/velocity/engine/trunk/ I \
think this is version 1.6.x because it is listed on \
http://velocity.apache.org/download.cgi But I'm not sure. 

When I was playing with the Velocity Template Engine I got a NullPointerException. \
Maybe it is because of my unusual configuration that this exception didn't occured \
before to others. But in my opinion this kind of Exceptions may never occur. 

To be specific, the Exception is thrown on line 225 in Foreach.java 
if (!hasNextName.equals("velocityHasNext")) 
When the variable hasNextName equals null
hasNextName is a deprecated config setting. It is assigned on line 210: hasNextName = \
rsvc.getString(RuntimeConstants.HAS_NEXT_NAME);

The included patch makes it NullPointer save: if \
(!"velocityHasNext".equals(hasNextName))
