Solutions

1. Change the primitive field to its wrapper type (e.g. Integer instead of int) if null is valid.
2. Ensure the database column is NOT NULL or provide a default value.

When it happens

Trigger: Null is assigned to a primitive-typed persistent property.

Common situations: Loading a nullable database column into a primitive field, or explicitly setting null on a primitive property.
