zero as a primary key [message #1177116]

Is there a way to set eclipselink.allow-zero-id using the "TopLink legacy" eclipseLink configuration and API?
We're migrating from TopLink to EclipseLink for many of our legacy applications.
We do NOT intend to switch them to JPA.
TopLink allowed zero for a primary key and EclipseLink is throwing an exception.
We've found solutions for JPA, but would like to apply this property in a non-JPA context.

Thanks

The eclipselink.allow-zero-id property is equivalent to the static org.eclipse.persistence.internal.helper.Helper.isZeroValidPrimaryKey boolean, which you could set in a session event method or customizer. This property was deprecated though in favor of using "eclipselink.id-validation" which you would call session.getProject().setDefaultIdValidation(IdValidation.NULL) in a customizer/event to use.

Best Regards,
Chris
