# The Ingredients and Roadmap of Rebooted Java EE 8 and 9

After one year vacations Java EE 8 was rebooted and is going to be optimised to run on hypervisors and / or container environments. Java EE 8 will focus on the following areas below -- it is a proposal and very likely to change in the JCP process:

Programming Model

Extend for reactive programming
Unified event model
Event messaging API
JAX-RS, HTTP/2, Lambda, JSON-B, (...)

Packaging

Package applications, runtimes into services
Standalone immutable executable binary
Multi-artifact archives

Key Value/Doc Store

Persistence and query interface for key value and document DB


Eventual Consistency

Automatically event out
changes to observed data structures

Serverless

New spec - interfaces,
packaging format, manifest
Ephemeral instantiation

Configuration

Externalize configuration
Unified API for accessing configuration

Multitenancy

Increased density
Tenant-aware routing and deployment

State

API to store externalized state

Resiliency

Extension to support client-side circuit breakers
Resilient commands
Standardize on client-side format for reporting health

Security

Secret management
OAuth
OpenID



The choices are pragmatic and will make Java EE an even more productive platform. I'm only missing a slightly extended and modernized "Concurrency Utilities for Java EE" (jcp.org/ja/jsr/detail?id=236). Particularly the ThreadPool configuration and Backpressure could be easily standardized just by agreeing on features from https://docs.oracle.com/javase/7/docs/api/java/util/concurrent/ThreadPoolExecutor.html. Particularly useful would be the integration of the statistics (e.g. Bulkheads) with the Health Check API.


Also a standardized management API (not proposed) would simplify the creation of application images through a unified API.


Java EE 8 and 9 will come at light speed to an application server vendor near you. Java EE 8 is expected to be delivered in 2017 and Java EE 9 in 2018.


Oracle is listening now, take the chance and participate at the survey (takes a few mins): glassfish.org/survey
