You will need to attach your DDL to a new Jira request so I can attempt to reproduce it

I'm curious though as to what version of Roo you are using. With the current code, at line 151, I am doing an NPE check for the inverse table of a many-to-many relationship. Just wanted to make sure I am handling the condition somewhat more gracefully.
