* Fixed failing test which was ignoring a required (not null) column
* restored test to original, catching DriverException which also catches ConstraintViolationException
* catch ConstraintViolationException again
* removed unnecessary field from this test
* clobfield should be nullable
* clobfield now is nullable
* removed autoincrement since whenever this strategy is enabled, oracle would not throw constraint violation exceptions (needed for setValues), which mysql still does
* this field does not auto increment anymore
* mark integerfield as primary, since it is not getting marked as such through auto increment anymore,
integerfield default always has been 0 instead of null
