How are you enhancing your Entities?
I have performed further testing by amending a query to be surrounded by

Ok, switched to buildtime enhancement and getting different problems
now!! Switched to working with a basic java project to resolve all the
problems.
When attempting to use :-
Account account = em.find(Account.class, JL);

version of openjpa library).
Simply delete the Account.class file, recompile Account.java and run
org.apache.openjpa.enhance.PCEnhancer on it.
