This patch has overrides for all the failing tests that do nothing.  These empty overrides
must be removed to reproduce the bug.

> Unenhanced generated id field of a primitive wrapper type causes NPE because the field
value is null.  This bug only occurs when the id field is an object type as primitive fields
are automatically initialized to 0.  I believe this is a critical bug because when using a
primitive field the system appears to work but the id field is always 0 which could cause
data corruption.  The following stack trace shows the bug:

> The attached patch reproduces this bug.  The patch is a clone of TestUnenhancedFieldAccess
that simply changes the id field to type Integer.
