  2. Pattern Matching in Java

    Srikanth Sankaran, Oracle
    Project Amber is an experimental OpenJDK project to develop major new language features for consideration for inclusion in future versions of Java. This talk will offer a highly speculative sneak preview of the advanced features currently in development for the Java language and virtual machine under this banner. In particular, the presentation will cover the motivation, challenges and state of development of a key Amber feature viz, Pattern Matching.

  3. Supporting Java™ 9 in Eclipse - A critical perspective

    Stephan Herrmann, GK Software SE
    The Eclipse JDT team has delivered full support for Java™ 9 right when the new version was released, just as we did for every version. In this session we will share some of the things we learned while working from an evolving specification. We will also discuss the impact of this new version specifically on tool-smithing for Java. Topics include:
    • Compiling is: Scanning, parsing, name resolving ... NO! There is no scanner.
    • Split packages are dead, long live split packages! Or: what's the meaning of a qualified name?
    • What defines Java 9? JLS, JPMS, JVM, javac, ecj, ...? Levels of specification and implementation, contributing to the meaning(s) of "Java 9".
    • What makes a Java 9 application? Source code, module descriptor, command line options, layer implementation ...
    • How do users handle all this? New configuration options, new errors / warnings, new assists.
    All will, of course, be illustrated by live examples in Eclipse.

  4. Java 10, 11: What the future holds

    Mala Gupta, Founder,
    With accelerated release cadence of Java every Spring and Fall, it will not just flaunt its top rank on TIOBE index 2018 but will also hold it for coming years. The session introduces latest developments in Java 10 and Java 11. It will also cover the projects Amber, Valhalla, Loom, and Panama - expected to bring new features in Java. Audience will understand how these features will help their applications to be leaner and faster.

  5. Reactive Microservices with Eclipse Vert.x

    Vidyasagar Machupalli, IBM
    Reactive systems are a new way to build distributed applications taking advantage of modern CPU architectures and using resources more efficiently. Building reactive systems is not straightforward. Building a microservices based architecture is also not easy. Many aspects need to be managed such as deployment facilities, service discovery, interactions between the services, resilence patterns, scalability and so on. Eclipse Vert.x is a toolkit to create reactive, distributed and polyglot applications on the Java Virtual Machine. Vert.x is incredibly flexible - whether it's simple network utilities, sophisticated modern web applications, REST services, high volume event processing or a full blown back-end message-bus application, Vert.x is a great fit and has demonstrated huge benefits in production. In this session, we explore how reactive microservices can be built easily with Vert.x and Kubernetes. The session will demonstrate how the combination simplifies the development, deployment and management of microservices.

  6. Supercharged Cloud Workspaces with Eclipse Che

    Shoubhik Bose, Red Hat
    Eclipse Che is a browser-based IDE providing on-demand container-based workspaces that include runtimes and IDEs. It is powered by a RESTful workspace server (with OpenShift or Kubernetes as underlying infra), plug-ins for languages, frameworks, and tools. In this talk, I'll speak about the architecture of Eclipse Che 6 and the power of container workspaces that help developers spin up consistent developer environments locally or on container orchestration services like OpenShift - to enabled developers to code, build and debug software projects from the comfort of a browser.

  7. Eclipse IDE Tips and Tricks

    Lakshmi Priya Shanmugam, IBM
    The Eclipse IDE is packed with a lot of features and capabilities that enable the users to be more productive in their day to day work. In addition to the existing ones, many new features are added in every release. This session will show several cool tips and tricks in action in the IDE that are invaluable to users in different aspects of development such as project configuration, editor management, source code navigation, coding and debugging. It’ll also highlight some of the useful tricks added in the recent Eclipse releases such as 4.9 and Photon.

  8. How deep is the mud: Identifying technical debt using Eclipse JDT

    Tushar Sharma, Researcher, Athens University of Economics and Business
    Poor quality code contributes to increasing technical debt and makes the software difficult to extend and maintain. Code smells capture such poor code quality practices. Identifying smells at different granularities and refactoring them help a software development team keep the software maintainable. Eclipse JDT offers a way to parse the Java source code in the form of abstract syntax tree and provides a mechanism to analyze it. In this session, I would like to present a code smell detection tool built using Eclipse JDT. I present the tool not only from a user perspective where I show how a Java developer can use the tool but also from a tool-development perspective where I provide the nitty-gritty of the source code analysis.

  9. Deploy a scalable WordPress implementation on Kubernetes

    Sudharshan Govindan, IBM
    You as a developer are looking to create best-of-class applications, and to do that you need to use the leading tools and platforms. This pattern shows you how to harness the full power of Kubernetes clusters and demonstrates how easy it is to deploy the world's most popular website framework on top of world's most popular container orchestration platform. Check out the Code Pattern for more details.

  10. Java Performance Testing for Everyone

    Shelley Lambert, IBM
    How can we more easily run performance benchmarks against Java SDKs and analyze and compare results? What information is coming out of some common open-source benchmarks and why might it be interesting? How can you incorporate performance tests into your continuous delivery pipeline? This talk addresses all of these questions and more as it surveys the performance testing story at AdoptOpenJDK. In this presentation, the common user story of determining whether a code change caused a performance regression guides us through the delivery pipeline at AdoptOpenJDK, but also introduces how you can leverage the automation from that open-source projects for your own testing requirements.

  11. OWASP and Secure Coding in Java

    Sulakshan Vajipayajula, IBM
    The session aims to bring awareness to OWASP and secure coding practices to defend against top 10 threats. Topics covered include, XSS, CSRF , Data protection, secure communication, scanning code for vulnerabilities among others.

  12. Please Behave Yourself: BDD and automating Eclipse RCP applications using JBehave

    Ankur Sharma, OpenText
    JBehave is a framework for Behavior Driven Development. It provides an easy way to express the test cases. This session will give a quick intro to it and will share with the audience how it can be used to automate the testing of an Eclipse RCP application using SWTBot and JBehave.

  13. Machine Learning for Java Developers

    Nasser Ebrahim, IBM
    Machine Learning is the current buzzword in technology and transforming the way we build solutions. As Java developers we've often wondered on the path to get started with Machine Learning techniques and frameworks. This talk is an experience sharing of an old time Java developer's journey into the Machine Learning space. We'll provide a high level overview of the machine learning fundamentals, discuss the tools and frameworks available to Java developers towards building Machine Learning solutions and demonstrate a ML use-case leveraging Deep Learning for Java frameworks. The talk is a starter guide for Java developers wanting to venture into Machine Learning.

  14. Eclipse OpenJ9: The best VM for the Cloud!

    Dinakar Guniguntala, IBM
    As more and more applications move to the Cloud (both public, private and hybrid), traditional java applications are now increasingly having to migrate to the Cloud as well. This has thrown a lot of challenges to the developers as well as the JVM to keep up with the new set of requirements. This talk explores every aspect of the DevOps cycle including provisioning, startup, running, idle and debugging vis-a-vis running a Java application. It looks at ways and means to get the best of running Java in containers. It also explains how Eclipse OpenJ9 has been optimized for each of these aspects. This includes the following:
    1. How to make the smallest Docker Image (disk size) and why? Explores docker image build techniques and effect of Image size on provisioning and build times.
    2. Container limits (CPU and Memory) vs -Xmx. This explores why setting -Xmx is no longer recommended and why it is better to use container limits.
    3. Use of a class cache for fast startup and scaling.
    4. Idle Optimizations. Or how to use the least amount of resources on Idle.
    5. Debugging tips for Java applications in Kubernetes. Use of MXBeans to dynamically gather debug info.

  15. Scaling Eclipse on HiDPI Monitors

    Niraj Modi, IBM
    Eclipse SWT started supporting HiDPI monitors from past two years. SWT approach to handle HiDPI on Windows and GTK2 is quite similar, the way it handles the Point/Pixel geometry. In 4.8 we have completeley rewritten HiDPI support for GTK 3 platform. Earlier the HiDPI support from GTK side was very minimal. So we ended up implementing HiDPI support in SWT itself. Since GTK3 started its support recently, We had to adapt to newer API. This presentation covers
    • Point/Pixel geometry
    • The challenges encountered
    • How the common approach is arrived at
    • How scaling is done in case higher resolution images are not available/or for the existing applications which are not DPI-aware
    Attendees should be using Eclipse Platform or SWT toolkit with basic code knowledge and will learn how to approach their application based on Eclipse to work with HiDPI monitors.

  16. The fundamentals of Functional Programming with Kotlin

    Abhay Sood, Go-Jek
    Kotlin supports functions as first class citizens. This is arguably the most important feature of Kotlin. It opens up a whole new style of programming - Functional Programming (FP). Kotlin seems to provide a great balance between OOP and FP. Making it a great language to slowly learn the concepts of FP without having to go through the huge learning curve all at once. The goal of this talk is to help you understand the concepts behind functional programming, help to change the way you think, and thereby help you in becoming a better developer. We’ll also go through a few real world examples in Kotlin where thinking functionally can help you in writing cleaner, safer and reusable code. You surely won’t become a functional programmer after this talk but let me quote from the famous essay on why functional programming matters matters: “… it (FP) expresses an opinion about what makes programs better. It backs this opinion up with reasons why modern functional programming languages are more powerful than imperative programming languages. But even if you don’t plan to try functional programming tomorrow, the lessons about better programs are valuable for your work in any language today.”

  17. Implementing Functional Patterns - a comparison of Scala and Java

    Pushkar N Kulkarni, IBM
    Functional programming patterns can help you structure your code better, improving its readability and reusability, while reducing the likelihood of bugs. For almost a decade, languages like Scala and Clojure were the only tools available to implement functional patterns in code running inside a Java Virtual Machine. Java 8 changed this picture with the introduction of the much awaited lambda expressions. Today, what was achievable only through Scala, can also be implemented using the new Java language features. This talk will focus on the syntactic comparison of these two languages in the context of realising functional programming patterns, trying to evaluate which one of them has a higher expressive power.
