Hi.
I tried to execute a code like this, and I got a stack trace.
JDOPersistenceManager jdopm = (JDOPersistenceManager) pm;
QProductClass cand = QProductClass.candidate();
JDOQLTypedQuery<Product> tq = jdopm.newJDOQLTypedQuery(Product.class);
List<Product> prods = tq.filter(cand.name.ne(value)).executeList();

I think this line explains the problem with the plugin.
