Java EE の戦略アップデート (2016/08/09 : JCP Executive Committee)

2016/08/09 JCP の Executive Committee のミーティング (Executive Committee Meeting Minutes for August 9 2016) がありOracle の Java EE/WebLogic 系製品の責任者 (Oracle Group Vice President ) である Anil Gaur さんから、今後の Java EE の戦略に対する説明がされたようです。
※ Anil さんは、元 Sun で Java EE/GlassFish の開発チームをまとめていた方。

* エンタープライズのプログラミング・スタイルが変わっている。
* 旧来のアプリケーション・サーバでは、複数のアプリが同一 アプリ上 アプリケーション・サーバで動いていたが、今は単一のサービスやアプリが、それ専用のモジュール化された実行環境でクラウド上にデプロイされている、Java EE をこうした次世代のアプリ開発に対応できるようにしたい。
* 新しいプログラミング・モデルは、大規模にスケールする分散アプリを構築するためにリアクティブ・スタイルのプログラミングを取り入れ疎結合化する必要がある。
* また、HTTP/2, 設定、状態管理、Eventual Consistency(結果整合性)、マルチテナンシー、O-Auth, OpenID Connect 対応にも注目している
* 現在は、Java EE の一部の大規模ベンダーに相談しているが、今後 Java Champion や Java ユーザ・グループにも相談する予定。

以降 EC メンバーとの Q&A
[Q] Werner Keil
Java SE プラットフォームは、今後リリース・サイクルを早めることを計画していると聞いていますが、このリリース・サイクルは Java EE にも当てはまりますか?
[A] Anil
Java SE とは切り離して考えてほしい。いくつかの機能は Java SE 8 をベースにするだろうし、Java SE 9 に依存する部分もあるでしょう。

[Q] Martijn Verburg のチームとコラボレートする計画はありますか?
[A] Anil
2つの計画が一緒になる事を期待したいと思います。Oracle は Red Hat にこの件について話し合いを持ちました。しかし現時点では明確な答えはありません。

[Q] Alex Blewitt

[A] Anil
Java EE 8 は後方互換性を壊すのではなく、オンプレミスでも動作するでしょう。今までと同様に、専門家グループがより広いコミュニティからのフィードバックを元に、リリースに関して最終的な範囲やパッケージングを決定するでしょう。

[Q] Mark Little
私は、Red Hat が Oracle と話し合いを持った事を確認しています。そして Red Hat は でプロトタイプを実装する際に Oracle と協業したいと言っていました。

その他、Steve Wallin、Bruno Souza、Matt Schuetze などから追加の質問、意見が寄せられてました。詳しくは、下記原文をご参照。


Java EE strategy
Anil Gaur, Oracle Group Vice President with responsibility for Java EE and WebLogic Server, gave a brief verbal presentation on Oracle’s Java EE strategy. He noted that enterprise programming styles are changing – more and more applications are distributed in nature and get deployed in cloud environments. Rather than traditional appservers that typically run multiple applications, apps are now distributed and deployed in the Cloud via modular runtimes dedicated to a single application or service.

We would like the future of Java EE to be viable to next generation of applications. These apps are composed and deployed differently in cloud and require flexibility, reliability and scale. The platform needs a new programming model that’s geared towards reactive style programming for building large-scale distributed applications that are loosely coupled. In addition, we would like to see HTTP/2, Config, State management, Eventual Consistency, Multi-tenancy, O-Auth and OpenID Connect get included in the platform. Oracle is talking to large Java EE vendors, and will soon consult with members of the community such as Java Champions and Java User Groups. He then asked for questions.
Werner Keil said that we had heard that Java SE would transition to faster release cycles. Would this also be reflected in Java EE? Anil replied that they intended to decouple from Java SE as best they could. Some features would be based on Java SE8 while others would depend on Java SE9.

Martijn Verburg asked whether there were plans to collaborate with the team. Anil responded that he would like to see the two efforts come together. Oracle has spoken to RedHat about this but there is no definitive answer yet.

Alex Blewitt asked about cloud-based provisioning, noting that Credit Suissse has some very sensitive data and would therefore want to run on-premise instead of “in the cloud”. Anil responded that Java EE8 will not break backward compatibility and noted that it will be possible to run Java EE8 on-premise. As always, the Expert Group will decide the final scope and packaging of the release with input from broader community.

Mark Little confirmed that RedHat has spoken to Oracle, and said that he hoped that they could collaborate, perhaps by prototyping at

Steve Wallin said that IBM has also had discussions with Oracle. He asked whether Oracle was considering a completely new platform. Anil responded that he doesn’t want to pre-judge this; the community must decide. Steve asked what was missing from the current platform, noting that IBM has been able to deliver rapid deployment based on the existing platform. He thanked Anil for coming to speak to the EC.

Bruno Souza said that Java EE has historically been very open and participative – more so than other platforms – and consequently had been very good for the JCP. Going quiet for a year was very unhealthy and had damaged Java. He hoped that this would not happen again.

Anil said he understood. Oracle intends to work with the community and the JCP. They want to deliver something that developers will find useful and exciting.
Werner Keil asked when Java EE8 would be released. Anil said that the planned date will change, but he doesn’t yet have the details. He expects to be able to say at JavaOne.

Bruno asked whether Java User Groups and the Adopt-a-JSR program could help. Anil said he would welcome such community involvement.

Matt Schuetze asked what the high-level message is. Anil said that Java EE will continue to evolve. Some features will be more revolutionary, but exactly how things will be packaged has not yet been decided.
Werner Keil noted that is being decommissioned and asked where Java EE projects will be hosted. Anil agreed that they would be impacted by this change and that they are evaluating alternatives.

There being no further questions, Patrick thanked Anil for coming to talk to the EC. Anil responded that he expected to reach out to many EC members in the coming weeks.
