[jira] Commented: (OPENJPA-12) Default to strictIdentityTypes for JPA

I think it would be better to pass the TCK without any properties that change behavior. Does anyone know if Sun has a guideline regarding the configuration properties?

Re: [jira] Commented: (OPENJPA-12) Default to strictIdentityTypes for JPA
Sadly, I believe that a discussion of the properties permitted to pass the TCK is found in the TCK configuration requirements, which I believe is confidential and therefore out of bounds for this alias. I hope to be corrected. Craig On Aug 15, 2006, at 2:20 PM, Michael Dick wrote: I think it would be better to pass the TCK without any properties that change behavior.
