If you haven’t watched a talk on language stewardship and evolution in a while – I would highly recommend this one.

Brian Goetz, Oracle’s Java Language Architect, makes a brilliant, witty, and passionate case for pragmatic evolution of programming languages and provides compelling reasons why Java not only remains relevant as the top programming language and platform of choice but – even after 20 years – continues to deliver innovation that matters to the entire IT software ecosystem, including 9 million Java developers and those building software with alternate languages on top of the Java runtime.

This is bigAt JavaOne a few weeks ago, Oracle made available the Java ME 8.1 Developer Preview release for the Freescale FRDM-K64F (“Java ME 8.1 in 190 KB RAM”) and announced the upcoming full release of Java ME Embedded 8.1 (press release).

On Monday this week, we followed up as promised and posted the General Availability (GA) releases of Oracle Java ME 8.1 and the Oracle ME SDK 8.1.

Oracle Java ME Embedded 8.1 and ME SDK 8.1 New Features and Enhancements

  • Support for ARM Cortex-M3/-M4 micro-controllers
  • Updated Raspberry Pi support 
  • Updated Developer Preview on FRDM-K64 with mbed
  • Improved support for two additional Qualcomm Gobi device families
  • New communication, security, and networking features
  • New support for Eclipse IDE, including major update of the Eclipse MTJ plugin
  • Developer improvements: Tooling over USB, heap analysis, faster communication
  • A number of smaller enhancements and fixes

Java 8: Truly Scalable

With this release, Java ME 8 now fully lives up to its design promise of delivering a feature-rich Java 8 platform that scales from powerful embedded systems all the way down to resource-constrained singe-chip micro-controllers with as little as 128 KB of RAM.

Developers can now rely on a consistent, standards-based programming model and platform that allows true code reuse from large to small solutions … in most cases the same, unmodified application binary will run across the entire range of target devices – irrespective of the underlying hardware and software differences. This means faster time-to-market, improved security and flexibility, and the ability to deliver more product value, faster

No other embedded software technology can do that today.

Welcome to Java ME 8!

Last month, Java 8 was launched. Last week, the Java Micro Edition (ME) 8 specifications were approved

Today, we are announcing the general availability (GA) of the Java ME 8 release.

This release is the culmination of a two-year effort driving a major update of the Java ME technology as a modern embedded software platform, purpose-built as a foundation for new services in the Internet Of Things. We are closely collaborating with industry partners and are seeing strong interest and adoption in Java ME 8 across a number of markets such as wireless modules, automotive, smart sensors, healthcare, industrial automation, smart energy, logistics, and others.

Top 10 Features of Java ME 8

Java ME 8 has been designed to enable advanced embedded software intelligence and increased product value for a wide range of use cases and solutions while maintaining very low system requirements. Top 10 features include:

  1. Aligned with Java 8 for efficient development
  2. Designed for Embedded
  3. Highly portable and scalable
  4. Consistent across devices
  5. Advanced application platform
  6. Modularized software services
  7. Client domain partitioning
  8. Direct access to hardware devices
  9. Compatible with standard APIs
  10. Enhanced embedded tooling

For more information, please see the screencast “Java ME 8: Top 10 Features”.

What We Are Releasing Today

Todays release comprises of several of components:

Java ME 8 TCK (Technology Compatibility Kit) and RI (reference implementation):

  • Java ME Connected Limited Device Configuration (CLDC) 8 (JSR 360
  • Java ME Embedded Profile (MEEP) 8 (JSR 361)

Oracle Java ME Embedded 8 product implementations and tooling:

  • Oracle Java ME Embedded 8 product implementations for several embedded platforms (see below)
  • Oracle Java ME SDK (Software Development Kit) 8 for embedded software development 

Oracle Java Platform Integrator (OJPI) releases for Java ME Embedded 8:

  • Enables Oracle partners to deliver value-add products and services based on Java ME Embedded 8 (OJPI information)

Support for the following platforms:

We are also planning on bringing Oracle Java ME 8 to additional platforms such as micro-controller-based devices – please stay tuned.
