World is moving fast towards parallelism. It will soon be seen that parallelism is the default nomenclature of the new software design. As a core member of Java Platforms Team, I want to bring the fact that how programming languages are leveraging the power the parallelism in this world of many core processors.

Though parallelism is the new demand, it is extremely hard generate performance on parallelism. We need to learn "the best practices" for parallelism.

      The Eclipse Foundation project Vert.x is a toolkit for developing polyglot reactive applications on the JVM. One can develop applications on Vert.x using not only JVM languages like Groovy, Ceylon but also languages like JavaScript and Ruby. Vert.x leverages event-driven and non-blocking techniques with the intention to help developers write high performant applications that are resource efficient.
       
      In this presentation, I will demonstrate the Vert.x way of architecting and developing applications. I will develop a few Verticles talking to each other through the event bus and expose the functionality through HTTP. I will use Groovy for most of my code examples along with JavaScript and Java to demonstrate the polyglot options.

      The Eclipse Platform is based on OSGi and OSGi is a model to modularize Java applications at runtime. Unfortunately, not all Java libraries provide the necessary metadata required for OSGi. Thus, if developers want to consume a library, they have to generate the OSGi metadata themselves. This problem is solved by the Eclipse Bundle Recipes project. It provides a library of templates (the “recipes”) and tools that can be used to create OSGi bundles. You have a library that you'd like to use in your OSGi project? Then stop by in this session and see if the Eclipse Bundle Recipes (EBR) project already has a recipe for your. You will learn how easy it is to consume libraries from Maven repositories and turn them into OSGi bundles. We will also demonstrate how the recipes and build system can be deployed in to create bundles at large scale and consumed in your builds. Last but not least, we will also show you how to contribute recipes to the EBR project.

      The last few years have seen new computing trends like increased use of mobile devices, big data and a world connected with internet. This has made Java applications vulnerable to threats and attacks. With time, holes get exposed in cryptographic algorithms and security protocols. They then need to be replaced with stronger alternatives. This session will show how safety mechanisms have been built into JDK to automatically protect applications from weak algorithms and protocols such as MD2, MD5, RC4, weak RSA/DSA keys and SSLv3. A wide variety of security controls have been made available which range from automatic defenses to user friendly APIs. Several new security controls have been introduced in Java 8 and Java 9 platforms like SHA-3 hash algorithms, OCSP stapling for TLS and DRBG SecureRandom implementation. This session will benefit Java developers by introducing them of the many defenses present and available in the Java ecosystem.

      Eclipse Java Development Tooling or JDT has its own Java compiler at its core, aptly called the JDT Core consisting of the Java compiler and various tools including java model, search infrastructure, content assist, Abstract Syntax Tree Tools etc.  Java 9 is the latest entry in the Java world bringing along-with it a "module" of changes - so to speak.  Any change in the language standards affects JDT directly. While some of the earlier language specification changes affected only the compiler, Java 9, in contrast, has a direct impact on user who uses Eclipse IDE for creating and managing Java Projects. Java 9  introduces the concept of "Modules" which affects JDT from the compiler level to the project dependency layer affecting a normal user. Support for this feature will be dealt with, in detail, in this talk.

      This talk would start with a brief overview of the Java 9 features especially the "module" feature that have direct impact on Eclipse users,  describe the JDT support for features, touch upon some of the design aspects, and would conclude with a demo of Eclipse JDT for Java 9.

      Searching in big databases is the need of the hour. With ever growing applications and customer base, quicker search over the data helps you survive. Modeling Frameworks sit at the core of modern software. The increasing complexity of business requirements are reflected in the increasing complexity of the modeling framework. What if you could query the complex models within seconds? This is just one use case of VIATRA Query.

      VIATRA Query is an Eclipse project. Initially conceived by the Budapest University of Technology and Economics, VIATRA is an Event-driven and Reactive Model Transformation Platform.  We have used VIATRA Query to create a small search engine for Ecore models of EMF using Natural Language Based Rule Engine and would like to share our experience with it.

      VIATRA Query enables the user to query the EMF models without having to manually traverse them. Complex queries can be converted into patterns. Parameters to models can be passed at runtime, something which is crucial to any query engine. The idea of creating a search engine using VIATRA Query opens up new and innovative ideas of working with Eclipse Modeling Framework. To know more about the algorithm behind this technology or how we made it work, please join us at the Eclipse 2017 Summit!

      CDCs are “Asynchronous Integration Tests”.CDC stands for Consumer Driven Contract. We can now forget about bringing up all the microservices to test the integration between different microservices.This makes integration tests as simple as unit tests. This is a must-have test for all microservices.

      The demand for parallel computing has always been on the rise when it comes to high performance computing. The innovations in hardware in the last decade have enabled developers to achieve this within a single machine which now offers multi-core, multi-processor capabilities. This is also becoming more and more popular compared to the traditional way of distributed computing which has its own constraints in terms of power and heat dissipation. Modern day developers want to leverage more on the multi-core/multi-processor architecture to achieve parallelism and Java Streams API offer them the best solution which allows the developers to break a larger task into smaller sub-tasks, process the sub-tasks in parallel and combine the results, while abstracting lower level multi-threading logic. While it sounds appealing, there are practical challenges in terms of getting the implementation right and debugging such implementations when there are issues. Essentially, the success of streams adoption largely depends on how robust the implementation is and how effectively one can do the trouble-shooting if something goes wrong. With that in mind, this session aims at addressing the best practices, common pitfalls with streams programming and provide debugging how-to for streams to make developers life easier.

      Optimized memory usage is a key to the success of enterprise applications on the cloud and developers often spend a lot of their time in trying to optimize their applications for memory footprint on the cloud. A deeper analysis of Java Heap reveals that 25-30% of live objects of most enterprise applications are strings and optimizing how strings are represented internally can give substantial benefit to the enterprise applications, without developers investing extra time. In this regard, there has been a significant effort to optimize string representation in JDK9 which would give significant off-the-shelf benefit to all the applications moving to JDK9 in terms of memory footprint. This session would cover all the string optimizations implemented in JDK9 in detail and a live comparison of Java Heap between JDK8 and JDK9 to demonstrate the real optimization that the application would get by just adopting JDK9.

      While ES6 generator patterns are designed to empower javascript language with iteration capabilities on heterogenous data structures in custom mannaer, the event-driven asynchronous programming model of Node.js transforms this feature into an interesting semantics in the execution flow control with un-precedented potential in managing concurrency.

      The session talks about how the generator pattern helps in iterating over deeply nested structures in a repeatable manner which follows a yield-resume pattern. I show a couple of real-world use cases where this approach helps in addressing performance / scalability / concurrency issues in large scale node.js applications, with an associated demo.
