You need the API to be built with Java8 since there are javax.jdo.query classes 
LocalDateExpression, LocalTimeExpression, LocalDateTimeExpression, 
OptionalExpression that support Java8 classes.

[jira] [Commented] (JDO-750) Change development environment to JDK 1.8

I'm not sure that the specification needs to identify the java release version. 
But the tck does.

Is there anything in the api that requires java 8?

I'll propose that the tck for 3.2 requires java 8. The tck for 3.1 already 
requires java 6. We can document the java requirements in the release notes.

[jira] [Commented] (JDO-751) Support for Java8 Optional

Just looked again at the class file metadata available at enhancement time. 
Using field.getGenericType() you can get the generic type of the field. So we 
probably can disallow this case if we choose. That's my vote.

Tilmann: It might make more sense simply to say that the behavior of 
Optional is not defined. We cannot reliably detect this case.
