Modern software architecture is often broken. Slow delivery leads to missed opportunities, innovation is stalled due to architectural complexities, and engineering resources are exceedingly expensive.
Orkes is the leading workflow orchestration platform built to enable teams to transform the way they develop, connect, and deploy applications, microservices, AI agents, and more.
With Orkes Conductor managed through Orkes Cloud, developers can focus on building mission critical applications without worrying about infrastructure maintenance to meet goals and, simply put, taking new products live faster and reducing total cost of ownership.

Mocking is an essential part of unit testing, and the Mockito library makes it easy to write clean and intuitive unit tests for your Java code.
Get started with mocking and improve your application tests using our Mockito guide:
Spring 5 added support for reactive programming with the Spring WebFlux module, which has been improved upon ever since. Get started with the Reactor project basics and reactive programming in Spring Boot:
Since its introduction in Java 8, the Stream API has become a staple of Java development. The basic operations like iterating, filtering, mapping sequences of elements are deceptively simple to use.
But these can also be overused and fall into some common pitfalls.
To get a better understanding on how Streams work and how to combine them with other language features, check out our guide to Java Streams:
Explore Spring Boot 3 and Spring 6 in-depth through building a full REST API with the framework:
Yes, Spring Security can be complex, from the more advanced functionality within the Core to the deep OAuth support in the framework.
I built the security material as two full courses - Core and OAuth, to get practical with these more complex scenarios. We explore when and how to use each feature and code through it on the backing project.

Spring Data JPA is a great way to handle the complexity of JPA with the powerful simplicity of Spring Boot.
Get started with Spring Data JPA through the guided reference course:
Refactor Java code safely — and automatically — with OpenRewrite.
Refactoring big codebases by hand is slow, risky, and easy to put off. That’s where OpenRewrite comes in. The open-source framework for large-scale, automated code transformations helps teams modernize safely and consistently.
Each month, the creators and maintainers of OpenRewrite at Moderne run live, hands-on training sessions — one for newcomers and one for experienced users. You’ll see how recipes work, how to apply them across projects, and how to modernize code with confidence.
Join the next session, bring your questions, and learn how to automate the kind of work that usually eats your sprint time.

At the very beginning of last year, I decided to track my reading habits and share the best stuff here, on Baeldung. Haven’t missed a review since.
Here we go…
1. Spring and Java
>> Proposed schedule change for JDK 9 [mail.openjdk.java.net]
This had to go first.
Not entirely unexpected, Java 9 got delayed by 4 months, which places GA in July of next year.
>> Private methods in interfaces in Java 9 [joda.org]
Java 9 is adding private methods on interfaces. Yes – you read that right 🙂
>> Java EE 8 Delayed Until End of 2017, Oracle Announces at JavaOne [infoq.com]
More clarity around the schedule and timeline of Java EE 8.
>> Feedback needed – Which constraints should be added? [beanvalidation.org]
A very quick survey asking for feedback on the exact constraints that should become part of the new bean validation standard.
Definitely worth voting on if you’re using the standard (and you probably are).
>> How to simplify JPA and Hibernate integration testing using Java 8 lambdas [relation.to]
Cool to see some Java 8 goodness in Hibernate.
>> JHipster 3.7 Tutorial Pt 3: Secure Service Communication Using OAuth2 [stytex.de]
A quick exploration of the new UAA functionality in JHipster – something I’m planning to make time to experiment with as well.
>> Complete Guide: Inheritance strategies with JPA and Hibernate [thoughts-on-java.org]
A good handle on inheritance strategies is a central aspect of understanding and working with JPA and Hibernate – and this article is a good way to brush up on the fundamentals.
>> JavaOne 2016 – Audience Gets a Glimpse of the Power of JShell [infoq.com]
JShell is one of the features I’m most excited about when Java 9 is going to drop.
>> Resource leakages: command pattern to the rescue [plumbr.eu]
Look – this isn’t new by any stretch of the imagination. Read it anyways – it might lead to code that behaves better.
>> Oracle Gives NetBeans to the Apache Foundation [infoq.com]
An unexpected move from Oracle, with hopefully positive consequences for the project.
That being said, that may also mean that the current Oracle team will slowly but surely be pulled from the project, which will definitely also have an impact.

2. Musings
>> Are you guilty of over-engineering? [frankel.ch]
This write-up is a good example of why TDD is so very useful. Design is the primary reason to do TDD – a design that almost always leads to fewer unnecessary abstractions like the one described here.
>> Old Geek [tbray.org]
It’s always baffling and sad to realize just how different the tech landscape looks over a certain age. It’s really a shame and easy to forget if you’re not there yet.
>> Here’s how broken today’s web will feel in Chrome’s secure-by-default future [troyhunt.com]
These changes are coming to Chrome (first) sooner rather than later. A bold step in the right direction – and one that’s especially interesting if you own a site.
>> Wherefore Art Thou, Tech Debt? [daedtech.com]
A insightful read about how different shops operate and about common patterns across the industry. Clearly a post born out of experience – and a hint of serenity that comes with that experience.
If you’re not doing consulting you’ve definitely seen some of these yourself but likely not all.
>> What 60,000 Customer Searches Taught Us about Logging in JSON [loggly.com]
It’s always fun to read up on how the industry doing logging, and “start logging in JSON now” is a message I fully agree with.
