Now that I have added that, when I do an update it is going into a
looping condition.

Here is part of the stack trace -

This is happening on the udpate of the enitity I added the queryhint to
on the find.
Seems like it keeps circulating between the CpTransCoverage entity and
the CpTransaction.

Any ideas on this one?

Sorry...  accidentally hit send too early.

Here's the info about the refresh hint:

esh

I apologize for giving you information that solves a more complex
problem than the one you are encountering in my initial response.  The
cache usage setting relates to how EclipseLink will determine whether an
object exists or not, rather than a simple refresh.
