| Hi,
I am working on a project using JPA with Hibernate implementation. I declared an entity using strategy GenerationType.SEQUENCE.
I also declared to use "hibernate.id.new_generator_mappings" with false value.
When trying to insert a new record for this entity, below was the exception:
Exception in thread "main" java.lang.NullPointerException
