Open source and J2SE,
living together in perfect harmony
Side by side on my computer keyboard,
Oh yeah, why can't we?
Java has been the springboard for some of the most successful open source projects today including JBoss, NetBeans, and Eclipse. Several folks though have felt the missing piece was an actual open source implementation of the runtime. Some view Sun's stewardship of Java and the JCP as being too controlling, while others believe it is an essential benign rule that preserves the integrity of the language. The view taken by Sun execs is that the JCP is essential to preserve portability while preventing forks in the language (as Microsoft once attempted with proprietary extensions). Should these occur, they could compromise a user's expectation that a Java program, once written, can run anywhere. Advocates of open source, however, deny this would occur and cite successful projects in which the benefits of fast innovation and widespread adoption have been fueled by having an open source community of developers who drive the implementation forward.
Earlier this year the Apache Foundation announced the Harmony project. Its aims are to write an open source version of J2SE from scratch. Given that specifications for J2SE are freely available, one question might be why such a move hasn't occurred before? In the FAQ for Harmony, Gier Magnusson from Apache states: "While the Java Community Process has allowed open source implementations of JSRs for a few years now, Java 5 is the first of the J2SE specs that we are able to do due to licensing reasons" (http://mail-archives.apache.org/mod_mbox/incubator-general/ 200505.mbox/%[email protected]%3E).
Rather than reinvent the wheel, after the initial announcement it seems that the plan is to try to pollinate the project with code and ideas from existing Java runtimes. At JavaOne Geir said: "There is a lot of software out there that we are hoping can be donated. We are hoping that we will get seeded with some code from existing production Virtual Machines." This is an invitation to the big guns of software and mom and pop developers, many of whom have either privately or openly tinkered with creating their own implementations of Java.
There are several potential Harmony contributors who might be in Geir's sights to step up to the plate. BEA has a very good JVM implementation in JRockit (www.bea.com/framework.jsp?CNT=index.htm&FP=/content/products/jrockit), while Kaffe (www.kaffe.org/) is a clean room implementation of the JVM.
Making Harmony succeed, however, requires more than just a JVM, as J2SE contains many lines of code in the actual class libraries, all of which need API compatible reimplementation. Due to licensing and IP issues this most likely must be done in an environment without reference to the existing Sun J2SE source code base, so the hill to climb is steep and high one.
I usually don't pay much attention to the cries of doom issued by execs of any company that has a vested interest in whether open source Java should succeed or fail, but I was surprised to hear James Gosling, when asked about Harmony, raise the issue of why Apache wants the Harmony license to be different from the existing J2SE one. He said: "I understand why they would like it to be different. From our point of view that would actually be more destructive than helpful. It boils down to forking: they believe that the ability to fork is an absolutely critical right" (www2.vnunet.com/lite/News/1163182). His voice is one I respect and should be listened to as words of wisdom and caution so the worst case scenario doesn't become a reality. To ensure compatibility with J2SE, however, the harmony FAQ states that it will be verified against the J2SE Test Compatibility Kit. The TCK is published by the JCP and is the yardstick used by all ratified J2SE integrations (JCP or commercial) that to date has ensured no fragmentation exists and no compromise of integrity has occurred.
Whatever the outcome of the Harmony project, while I do understand the concerns of those who are frightened of fragmentation in the language, I am more excited by the prospects of having an open source implementation J2SE. This will enjoy the same benefits that other open source projects have experienced, where a community of like-minded, smart individuals who share the same goal can participate equally in the same code and knowledge base of ideas and innovation. Ideas, bug reports, and schedules are transparent and can be iterated in public toward the best solution. The momentum of the project becomes fueled by the feedback loop created by an alliance of like-minded individuals in a partnership of conviction. To those who don't believe this will work, ask not if the glass is half empty, but listen instead to the lyrical genius of Sir Paul McCartney and Stevie Wonder:
We all know that people are the same where ever you go
There is good and bad in everyone
Learn to live, we learn to give each other
What we need to survive, together alive

I agree with James Gosling's concern - there will always be holes in any specifications.
If there is only one single implementation, such undocumented behaviours can still be utilised after some preliminary investigations; but if more than one implementations is used by the majority of end-users, these undocumented portions could have different behaviour.
It may sound as if we shouldn't have used any unspecified "features" in a specification, but they are often the only workaround for certain tasks to date, due to the deficiency in the spec. Only by having a single major implementation can we do away with these problems easier, if at all.
Mobile messaging has been a popular communication channel for more than 20 years. Finnish engineer Matti Makkonen invented the idea for SMS (Short Message Service) in 1984, making his vision a reality on December 3, 1992 by sending the first message ("Happy Christmas") from a PC to a cell phone. Since then, the technology has evolved immensely, from both a technology standpoint, and in our everyday uses for it. Originally used for person-to-person (P2P) communication, i.e., Sally sends a text message to Betty – mobile messaging now offers tremendous value to businesses for customer and empl...

Organizations already struggle with the simple collection of data resulting from the proliferation of IoT, lacking the right infrastructure to manage it. They can't only rely on the cloud to collect and utilize this data because many applications still require dedicated infrastructure for security, redundancy, performance, etc. In his session at 17th Cloud Expo, Emil Sayegh, CEO of Codero Hosting, will discuss how in order to resolve the inherent issues, companies need to combine dedicated and cloud solutions through hybrid hosting – a sustainable solution for the data required to manage I...

As enterprises capture more and more data of all types – structured, semi-structured, and unstructured – data discovery requirements for business intelligence (BI), Big Data, and predictive analytics initiatives grow more complex. A company’s ability to become data-driven and compete on analytics depends on the speed with which it can provision their analytics applications with all relevant information. The task of finding data has traditionally resided with IT, but now organizations increasingly turn towards data source discovery tools to find the right data, in context, for business users, d...

Clearly the way forward is to move to cloud be it bare metal, VMs or containers. One aspect of the current public clouds that is slowing this cloud migration is cloud lock-in. Every cloud vendor is trying to make it very difficult to move out once a customer has chosen their cloud. In his session at 17th Cloud Expo, Naveen Nimmu, CEO of Clouber, Inc., will advocate that making the inter-cloud migration as simple as changing airlines would help the entire industry to quickly adopt the cloud without worrying about any lock-in fears. In fact by having standard APIs for IaaS would help PaaS expl...

You have your devices and your data, but what about the rest of your Internet of Things story? Two popular classes of technologies that nicely handle the Big Data analytics for Internet of Things are Apache Hadoop and NoSQL. Hadoop is designed for parallelizing analytical work across many servers and is ideal for the massive data volumes you create with IoT devices. NoSQL databases such as Apache HBase are ideal for storing and retrieving IoT data as “time series data.”
