Java debugging: how to debug Java code in IntelliJ, Eclipse, and jdb

An effective Java debugging strategy lets us pause execution, inspect data, and observe real execution rather than relying on vague assumptions. The complexity of the Java Virtual Machine creates unique challenges, but a focused approach will turn this complexity to our advantage. This guide will equip you with the tools to do this, looking at: By the end, you’ll have a practical workflow to debug Java reliably across local and remote environments.

Validate Spring Boot Upgrades with Traffic Replay

Spring Boot version upgrades—whether moving from 2.x to 3.x, 3.x to 4.x, or even minor bumps like 3.2.5 to 3.3.1—regularly introduce subtle, breaking changes that unit and integration tests miss. JSON serialization shifts, autoconfiguration reordering, and transitive dependency conflicts can silently alter your API contract.

Instant Java Client SDK, no spec required!

Learn how to generate a client SDK for a production service when you have no documentation, no OpenAPI spec, and no remaining team knowledge of the original Ruby code. This demo shows you how to capture real production data from a running app and transform it into a functional Java client library in minutes. Visit proxymock.io OR speedscale.com to learn more.

Spring Boot API Testing: A Practical Guide for Enterprise Teams

Enterprise Spring Boot APIs should be tested at three levels: unit tests for business logic, integration tests for external service behavior, and traffic replay for production edge cases. Most teams only do the first. This guide shows all three using a real Spring Boot application that calls external APIs (SpaceX, US Treasury) with JWT authentication. The kind of service that looks simple in development and breaks in production.

JRebel and XRebel: The Ultimate Power Duo for Java Development and Performance

Every minute spent waiting for your IDE to build, package, and redeploy code is a minute taken away from what matters most: writing better code. JRebel and XRebel give Java developers the power to eliminate redeploy wait times and catch performance bottlenecks in real-time — so your team can focus on shipping high-quality features faster.

Oracle JDK to OpenJDK: A Guide to Reliable Migration Testing

One of the most common infrastructure changes Java developers and operators are dealing with today is the migration from Oracle Java to OpenJDK. The reason is the licensing changes made by Oracle and the maturity of the OpenJDK distributions. The migration process is quite simple: replace the JDK, recompile the code, and redeploy the application. However, the differences between the two runtimes can lead to unexpected issues that are not caught by unit tests.

4 Steps to Take Back Control of Your Java Release Cycle and Manage Dependencies Better

Regaining control of your Java release cycle can dramatically improve build stability, security, and developer productivity. In this video, Perforce OpenLogic experts share practical guidance on Java dependency management, including how to audit dependencies, govern their use, and reduce risk in complex builds.

Navigating Spring Dependencies (Spring Boot and Framework)

Navigating Spring dependencies can be challenging. As many Java developers know all too well, the biggest risk in maintaining legacy Spring applications isn’t in the code you wrote — it’s in the web of dependencies you inherited. Hidden deep in your build files, these libraries can make or break your application’s ability to stay secure and up to date. In this video, OpenLogic experts explain how transitive dependencies in older versions of Spring Boot and Spring Framework can negatively impact your application's stability and security.

Most Popular Java Web Frameworks in 2026

Look, if you're starting a new Java web project in 2026, you should probably just use Spring Boot. With 14.7% usage in the 2025 Stack Overflow Developer Survey and a 53.7% admiration score among all web frameworks, it remains the default choice for modern Java web development. It has the largest ecosystem, best documentation, most active community, and strongest cloud-native support—now enhanced with built-in AI capabilities through Spring AI.
