Minutes: JDO TCK Conference Call Friday July 8, 9 AM Pacific Daylight Time (PDT)

[Craig Russell <cr...@oracle.com>]

Attendees: Michael Bouschen, Tilmann Zäschke, Craig Russell

NOTE: We have a new video conference. Please disregard the previous one.

Next meeting will take place on Thursday June 15 at 9:00 PDT.

Agenda:

1. New patch on JDO-751 "Support for Java8 Optional" https://issues.apache.org/jira/browse/JDO-751

Discussion continues in the JIRA

Persistent Object Model 6.4.3
java.lang.Optional types
JDO implementations must support fields of type Optional<T> where T is an Immutable Object Class types, java.util.Date, Enum types, or Persistence-capable Class types. They may be mapped nullable datastore types or to Optional<T> types at the option of the JDO implementation.

When instantiating an instance from the datastore, the JDO implementation would get the value v from the datastore and assign the field f = Optional<T>.ofNullable(v). When storing the field in the datastore, the persistence implementation would store the result of v = f.isPresent()?f.get():null.

Navigation in JDOQL via optional.optional seems to be an issue. It looks similar to navigating the Company model, e.g. WHERE this.manager.manager.name == ‘Michael’. AI: Michael try some experiments with queries and multiple navigations.

2. JDO 3.1: Need to go through change lists in JIRA for 3.1 RC1 and 3.1 to prepare JCP Change Log
