["Craig L Russell (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/JDO-751?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15367840#comment-15367840 ] 

Craig L Russell commented on JDO-751:
-------------------------------------

Starting to work on the specification:

Persistent Object Model 6.4.3

java.lang.Optional

JDO implementations must support fields of type Optional<T> where T is any supported Object type. They may be mapped to nullable datastore types or to Optional<T> types at the option of the JDO implementation.

> java.util.Optional provides a feature that is available in other languages. Since JDO 3.2 will be for Java8+ then it makes sense to add support for this as a "supported persistable type"
