Re: [ee4j-community] Oracle Java EE8 Issue Tracker Abandonment

Hi Werner,

The migrated issue for JPA at GitHub is

https://github.com/javaee/jpa-spec/issues/146

... which is closed and includes a link to the JPA community list thread that lead to this conclusion. You can continue this thread either via the issue at GitHub, or https://javaee.groups.io/g/jpa-spec/message/7

-- Ed

PS We did our best to preserve issue IDs as we migrated from Java.Net to GitHub. We also provided cross-reference links at the top Java EE web-page: http://javaee.github.io and http://jpa-spec.java.net does refer on to the current git-hub project page. As with any service discontinuation, when java.net was closed down, the information chain became harder to negotiate. We are sorry for that inconvenience.

Bill,
Thanks for the clarification. It often is indeed hard to find on the JCP pages, although https://jcp.org/aboutJava/communityprocess/mrel/jsr338/index.html clearly states 2.2.
Similar for other JSRs like CDI where only https://jcp.org/aboutJava/communityprocess/mrel/jsr346/index.html
showed the MR was CDI 1.2.
A case of "abandonment" would be this Java.net JIRA ticket for JPA 2.2: https://java.net/jira/browse/JPA_SPEC-146
Is there a follow-up on GitHub by any chance?

Thanks,

Werner

Thanks a lot Greg. Would be interesting to see how other people expect to
tackle this for the time being.

Do any other vendors here expect to support native Java 9 modules in the
short term?

It's confusing on the JCP web site, but it *is* JPA 2.2.? Here
<https://jcp.org/aboutJava/communityprocess/maintenance/jsr338/ChangeLog-JPA-2.2-MR.txt>
are the changes to JPA 2.1 that resulted in JPA 2.2.
