“Many of today’s vehicles already have ‘crash-imminent braking’ and other features,” says Perrone. “But up until now, the IIHS hasn’t really had a way to test how well these technologies work in real-world situations with cars traveling at highway speeds.”

In a festive room teeming with over 200 people, including many celebrated Java luminaries,
along with excellent food and drink, the 9th annual JCP Program Awards were handed out atop the majestic Hilton Hotel on Monday night. As the JCP states, “The Java Community Process (JCP) program celebrates success. Members of the community nominate worthy participants, Spec Leads, and Java Specification Requests (JSRs) in order to cheer on the hard work and creativity that produces ground-breaking results for the community and industry in the Java Standard Edition (SE), Java Enterprise Edition (EE), or Java Micro Edition (ME) platforms.”
The JCP added a new awards category this year for Adopt-a-JSR program participants, bringing the total to four: JCP Member/Participant of the Year, Outstanding Spec Lead, Most Significant JSR, and Outstanding Adopt-a-JSR Participant.
The room was full of good cheer, playful humor, a music band of Java developers, and enthusiastic appreciation of much that has been accomplished on behalf of Java technology in the previous year.
The nominees and winners in their respective categories
JCP Member/Participant of the Year
--Azul Systems, Gil Tene
--London Java Community (LJC), Ben Evans, Martijn Verburg, Richard Warburton, Graham Allan
The winner was Azul System’s Gil Tene. The JCP said, “Gil has worked diligently to provide clear advice on matters of Software Patents, IP and licensing that seeks to benefit both non-profits/individuals etc as well as organizations with vested commercial interests in Java. It's not easy delving into the depths of the legal aspects and the potential impacts of changes to the JCP, but with help from folks like Gil we're hopeful for a solid and fair outcome.”
Tene characterized his approach to the JCP as follows: “I represent Azul Systems on the JCP EC, but I try to apply an approach of ‘do the right thing first’ in my choices and positions. Coming from a small company that depends on Java and its ecosystem for its livelihood, I see my role as representing the interests of an entire sector of non-big-company commercial folks and of individual and professional developers out there, and providing some offset and balance to the normal mix of such boards.”
Outstanding Spec Lead
--Brian Goetz, Oracle
--Jitendra Kotamraju, Oracle
--Anatole Tresch, Credit Suisse
--Chris Vignola, IBM
The winner, Oracle’s Brian Goetz, was recognized, “For tirelessly working away at an incredibly complex JSR - JSR 335, Lambda Expressions for the Java Programming Language. From a community point of view, we've appreciated his willingness to listen and consider ideas from other technologists as well as spending time with groups of developers to understand the impact of Lambdas on Java.”
Goetz offered a statement in response to the award for his leadership in creating Lambda Expressions for the Java Language, which also won for most significant JSR. He said that lambdas, “represent a coordinated co-evolution of the Java SE platform, including the VM, language, and core libraries to provide developers with a powerful upgrade -- quite likely the largest ever -- to the Java SE programming model. We started this JSR in early 2010, but the topic of closures-in-Java had already been in play in the community for many years prior, and, of course, there was a broad diversity of opinions as to what direction, how far, and how fast to evolve the Java programming model. In the end, the most significant dimension of the challenge turned out to be: how do we integrate these new features in the language and libraries without them feeling grafted on after-the-fact. I think developers will find programming with this ‘new and improved Java’ to be a very pleasant experience -- I know I have.”
Most Significant JSR
--JSR 335, Lambda Expressions for the Java Programming Language
--JSR 344, JavaServer Faces (JSF) 2.2
--JSR 352, Batch Applications for the Java Platform
--JSR 354, Money and Currency API
--JSR 355, JCP Executive Committee MergeThe winner, as previously mentioned, was JSR 335, Lambda Expressions for the Java Programming Language, which the JCP praised as follows:
“This brings Java kicking and screaming into the modern programming language age and is seen as a catalyst for the second age of Java. It's underlying discoveries and improvements with regards to Type Inference has also resulted in a stronger JVM for all.”
Spec lead Brian Goetz, in picking up the award, remarked, “This is something we’ve been working on for three-and-a-half-years and it’s nice to be looking at it through the rear-view mirror.”
Outstanding Adopt-a-JSR Participant
--BeJUG, Johan Vos
--CeJUG, Helio Frota, Hildeberto Mendonça
--JUG Chennai, Rajmahendra (Raj) Hegde
--Morocco JUG and EGJUG, Mohamed Taman, Faissal Boutaounte
The winner was Morocco JUG and EGJUG, Mohamed Taman, and Faissal Boutaounte, who were praised, “For adopting JSR 339, JAX-RS 2.0 specification, along with many other JSRs. One JIRA issue filed by Morocco JUG on JSR 339 was classified as a ‘release-stopper’. A quick JIRA search using the ‘adoptajsr’ tag shows that most of the JIRA issues have been created by MoroccoJUG members. Several presentations and source code have been organized by these groups. Mohamed presented sessions about the upcoming technologies to widen the range of users in the future, especially Java EE 7 JSRs and spreading of community progress and contributions that make us encouraged to participate. Mohamed sent a clear message that Africa is here and is full of talented people who are willing to take it to the next level. Mohamed was responsible for translating an Arabic Adopt-s-JSR web page to allow more Arabs to participate.”
Taman said that, “Currently, I hold two positions, one as a Business Solutions Systems Architect and design supervisor and Java Team leader, at a big financial services company in Egypt, which affects all the country by building solutions affecting Egyptians every day, by providing more facilities for businesses and enhancing the economy… I am passionate about Java. I really love it and have fun coding, and love seeing it grow, day by day, as if it were my kid.”

Greg Bollella and Eric Jensen on the Future of Cyber-Physical Systems with Embedded Java and Berkeley DB
By Janice J. Heiss on Oct 17, 2011
The presentation offered a vision of the potential future of Cyber-Physical Systems (CPS), defined as, “a system featuring a tight combination and coordination between the systems computational and physical elements,” that was so powerful that even if the expectations turn out to be exaggerated, CPS technological change will, in a decade or so, significantly alter our lives in pervasive and unforeseeable ways. Bollella went so far as to say that CPS applications have the potential to dwarf the 20th Century IT Revolution.
He drew a contrast between where CPS applications are in use today and where they will be in use tomorrow.
Today: High confidence medical devices and systems; assisted living; process control (metal smelting, chemical plants, refineries); traffic control and safety; advanced automotive systems; energy conservation; environmental control (electric power, water resources, and communications systems); distributed robotics (telepresence, telemedicine); defense systems; manufacturing; smart structures; home automation; building automation; transportation (rail, air, water, road); retail systems (point of sale and monitoring); entertainment industry; mining; industrial control (power generation).
Tomorrow: Distributed micro-power generation; highly advanced autonomous driver assistance features; networked autonomous automobiles; networked building automation systems; cognitive radio (distributed consensus about bandwidth availability); large-scale RFID-based servicing systems which could acquire the nature of distributed real-time control systems; autonomous air traffic control; advanced industrial and home networked robotics; intelligent traffic control systems; intelligent autonomous power (gas/electricity); distribution systems; networked personal medical monitoring devices.
A lot to take in – the technology all around us growing in intelligence! In 2009, 3.9 billion embedded processors were shipped – the number is expected to double to roughly 8 billion by 2015. Some predict that by 2025 the number will be well into the trillions. And currently, an estimated five times more embedded software is written than all other software today. If the reality is anywhere close to the projections and estimates, we are in for an interesting ride on some intelligent transport.
Bollella went on to discuss telemetry, a term frequently used by NASA and defined as a technology that “allows remote measurement and reporting of information”. Central to telemetry is the idea that the information does not persist on the device after measurement. Uses of telemetry in the automotive realm include streaming operational data from the vehicle to the manufacturer’s IT system for analysis, services for vehicle operator, failure prediction, and feedback to design teams on wear and failure rates. For industrial automation, telemetry is used for failure prediction and to process monitoring and reporting
Bollella explained that his use of synchronization is idiosyncratic to database technology and involves two synchronized databases containing the same set of data and relationships. Any change in one database appears (after some indeterminate delay) in the other. The information on the device persists on the device as long as it does on the backend
The use cases for synchronization are widespread and include:
• Healthcare: Telemedicine, Home health systems, Mobile health practitioners
• Industrial: Manufacturing, Mining
• Energy: Smart Grid, Energy Management
• Entertainment: TVs, set top boxes, automotive rear-seat entertainment
• Distribution/Shipping: Everything from local deliveries to transoceanic cargo shipments
• Government: Border Control, Resource Management, Customs, Immigration, Land Management, Forest Service, etc
• Law Enforcement/Military: Police officers and soldiers in the field, also aboard Naval vessels
• Retail: Real time inventory linked to point-of-sale transactions
• Distribution/Shipping: Everything from local deliveries to transoceanic cargo shipments
Bollella acknowledged that serious development challenges remain. The current state of CPS connectivity is poor, with the vast majority being standalone. Given the highly connected world of social networking, mobile devices, and the web, this might be surprising. But it is important to consider that these are two technological areas have evolved in environments with different demands. CPS is focused on real-time, predictability, safety, security, and fault tolerance; the Web is a different matter.
CPS requires real-time with predictable control loops -- there are no standard communication protocols or Ethernet or “IP-over” functionality on devices. There are harsh environments, especially in spacecrafts, that can affect wired Ethernet, and there exists incompatibility of data formats and communication protocols with IT standards.
Perhaps of greatest importance, there has been little perceived need for CPS connectivity with devices. But this is changing rapidly, and with it, obstacles are being overcome as one of the major trends in embedded is connectivity development. Bollella admitted that there were a lot of unknowns going into the future, but the challenges are not insurmountable.
Oracle’s Eric Jensen took over and gave some details about the Oracle Berkeley DB and the Oracle Database Mobile Server, which he characterized as the best way to synchronize mobile or embedded applications that utilize SQLite or Berkeley DB with an Oracle backend. The embedded Java platform, when coupled with Berkeley DB and Database Mobile Server, has the ability to manage networks of embedded devices using existing enterprise frameworks in a way that could prove to be quite revolutionary
It will be interesting to look back in 10 years and see how much Cyber-Physical Systems have, or have not, changed the world.
