Mistake in documentation for 3.7.2 Composite Identifiers

Hibernate ORM
1

I believe I’ve found a mistake in the documentation.

Namely Section 3.7.2 Composite Identifiers states, that JPA requires the following from Composite Identifiers:

  • The primary key class must be public and must have a public no-arg constructor.
  • The primary key class must be serializable.

However in the release notes of JPA 3.2 it states: Primary key classes are no longer required to be public and serializable.

I’m assuming, this was simply not updated and no longer reflects the implementation. Therefore I can safely ignore these two points.

Correct, but it would be nice if you would create a PR to actually fix this :slight_smile:

Here you go.
