Ritika Maheshwari commented on OPENJPA-168:
-------------------------------------------
In the singleResult method of the kernel QueryImpl when null was returned I
threw an error using localizer property "not-unique".But this error message
does not correctly define the error so in the localizer.properties I added
another property as follows
not-unique: The query on candidate type "{0}" with filter "{1}" was \
configured to have a unique result, but more than one instance matched \
the query.
is-null: The query on candidate type "{0}" with filter "{1}" was \
configured to have a unique result, but no instance matched \
the query.
so the is-null error would be thrown for the null conditions.So I will apply
this on top of patch2
> sql optimize n rows query hint
