Null pointer exception does not point to a specific object/source code

IN the AccountCreation Object, I forget, well now commented out the @Inject for the UserSession object. When running through the Add new user workflow, at the end of the process, I get the stack dump below, however no Object reference is defined. Ie I have no idea which object was null. This should clearly tell me that I was trying to use the UserSession object, and it was null at the time I tried to use it. I have included the eclipse project.

Stack Dump:
