Ever seen a security-related issue that you felt should be reported? Unsure of how reporting a security issue is different than a regular bug? Developers of any level should know how to report a vulnerability. In this talk, we will talk about what CVEs are, some general vulnerability classifications, look at a few ways you can report security issues, as well as look at a few common mistakes.
This session introduces the OpenRewrite platform for automated source code refactorings and walks the audience through our efforts to integrate this platform into Eclipse and Visual Studio Code as part of the open-source Spring Tools.
Please give us a detailed overview of your session and why attendees will be excited to hear about it.
Ensure that you let us know:
Are you sick of slow JVM/Application startup? Well there is a new OpenJDK project called CRaC which is all about improving JVM/Application startup without using native images. Let me show you how it works and what is in for you.
What are you presenting

You have this cool new Spring Boot Application on Azure? You mean AWS right!? Nobody runs Java on Azure? Well they do! I will take away all the prejudice and will show you that your Java app shouldn’t be married to AWS but can run just as swiftly in Azure! In this session I tell and show you how you can leverage the powers of Azure when you are running a microservice application based on Spring Boot and how to integrate the platform into your Eclipse IDE making sure a smooth development experience is archieved.
Type Switches are now part of Java Language albeit with the preview tag. Though similar to traditional constant switch statements in terms of structure but they differ in multiple ways – they now accept type as an expression to switch – essentially they can “switch” on a type. Switching on a type is not as straightforward as switching on constant values – now a particular type can match multiple cases, thanks to type hierarchies. What happens if such a case occur? How does the implementation take care of this? What’s the byte code generated?
Not so long ago, Java lovers were engulfed by a mammoth change— the Lambda Expressions in Java 1.8! However, eclipsed by lambda, minor in its avatar, was an introduction of a new error message - “should not be used as an identifier,...; a prudent observer would know that we are discussing about _, an underscore, which was being removed as a legal identifier, quietly - And it was being promoted to being an integral part of the next wave — Patterns in Java! This talk is all about this major paradigm shift of Pattern Matching that's happening in Java Language now!
Jakarta EE 10 is packed with new features for simple development of modern, lightweight enterprise Java applications for the Cloud. The new Jakarta EE Core Profile enables developers to develop microservices based on Jakarta EE technologies with runtimes smaller than ever. Jakarta EE Core Profile even makes it possible to compile Jakarta EE applications to native images to reduce the footprint even further.
A small but vital step on a long road was made last year. The President of the USA signed an executive order towards improving the situation on cybersecurity. I
n this session you’ll learn more about what was ordered and how it’s the beginning of a significant change in how software will be developed, delivered and secured in the future – not just in the USA but world wide too.
It’s just there. Just like the stars, just like electricity, just like Java.
In the Java world Maven central is the most important single service. You can get Java SDKs and even container images from various vendors but Java code comes from only one place: Maven central.
Serving overt 10 billion requests a week, Maven Central is sooo boring, sooo reliable that it’s understandable that it’s mostly invisible. It’s just there.
Technology communities almost by definition need to be open, welcoming, diverse, and inclusive to do the most good for the most amount of people. Yet without adequate checks and balances technology communities have an unfortunate track record to be anything but – especially for people on the wrong side of power dynamics such as women and minorities.
Java/Jakarta EE is an important technology to support on Azure. Enterprise Java is a heterogenous ecosystem with as much as a third of workloads still running on Java/Jakarta EE application servers such as WebLogic, WebSphere/Open Liberty, JBoss EAP, WildFly, and Payara. This is particularly true for large enterprises that need to lift and shift their existing mission-critical, largely monolithic applications to Azure. Traditionally, Azure has not focused on strong support for such workloads but that is changing now and going forward.
Jakarta NoSQL is a new standard for accessing non-relational databases on the cloud. Cosmos DB is a best-of-breed planet scale NoSQL database on Azure that is compatible with MongoDB, Cassandra and Gremlin.
In this session we will see how to use these technologies together in cloud native Jakarta EE applications. Most of the session will be demos with a minimal number of slides.
This fast-paced, demo-driven, entirely slide free session will show you the many ways of effectively deploying a Java/Jakarta EE application to Azure. We will start by deploying a local Java/Jakarta EE application to basic IaaS on Azure. We will then deploy the same application to an entirely managed Azure PaaS. Finally we will deploy the application to Azure using Docker and Kubernetes. We will discuss the trade-offs of each approach on the way, offering guidelines for which approach might be best for your application on the cloud.
Enhancing diversity and inclusion in every aspect of technology is an essential conversation everyone should be a part of. In an increasingly interconnected world, we have a shared responsibility to ensure technology is a force that works to benefit everyone, countering structural sources of inequity where needed.
This session aims to jump start your personal diversity and inclusion journey by explaining the basics in simple terms with relevant examples for technologists. Concepts covered will include unconscious bias, privilege, equity, allyship, covering and microaggressions.
Domain-Driven Design (DDD) is an architectural approach that strongly focuses on materializing the business domain in enterprise software through disciplined object-oriented analysis. This session demonstrates first-hand how DDD can be elegantly implemented using Jakarta EE via an open source project named Cargo Tracker.
Cargo Tracker maps DDD concepts like entities, value objects, aggregates and repositories to Jakarta EE code examples in a realistic application. We will also see how DDD concepts like the bounded context are invaluable to designing pragmatic microservices.
Words like standard, de-facto, de-jure and open are frequently used and abused in our industry. The reality is that few people really understand what these words actually mean or how these ideas effect their own professional lives in the long and short term.
Before starting to develop any language applications you need to know the grammar of that language and have a language-recognizer tool which understands that language and generates the parsers using pre-defined language grammars. So main focus of this demonstration is about ANTLR4 tool. ANTLR is widely used to write interpreters and compilers for new languages, or to build tools and frameworks, or to analyze logs.
