STEPS
-----------------------
The issue can be reproduced at will with the following steps:

1. Set Up the 2 items and Order Configurations. Make sure one of these has the fields "Number of Layers on Ship Unit" and "Quantity Per Layers" fields populated and the other does not these values populated. 
2. Create an Order Release xml's to fit your domain (Location IDs and Domain Name and Packaging Unit/THU
3. Upload each XML.
4. Notice the xml with first item processes successfully as it contains the fields mentioned on the packaged item.
5. Note the xml with second item fails with the null pointer because the fields are NOT populated on the packaged item.
 
Since these fields are not "required" fields - it is not expected to be populated and should not error out.
