JIRA refused to accept my upload of a document that outlines my issues concerning the JPA generator. The file is available as a PDF or a Word docx. Both are refused with a message about a missing token. I do have a JIRA login. I will email it directly to you but I'd like to have it recorded on JIRA.

It would be good to get something in the issue tracker for this problem. I haven't used the auto-generation of new JPA controllers. I usually create my own so I haven't come across this issue...but I'll see if I can replicate this problem. I may not personally be able to make the repairs for this (at least not anytime soon), but it should at least get in the tracker so that we can have it in the queue. It does sound like this code needs updating. It sounds like you have a good strategy for moving forward with your class. Hope all goes well.
