Deadlock is a common problem in applications where multiple threads block each other while waiting for a resource. This can cause the application to stall or slow down. To fix deadlocks, you can define a specific order for locks using hash codes, use timed lock attempts, or analyze thread dumps to detect and prevent deadlocks.
This post helps you troubleshoot JVM deadlock issues in ServiceNow MID server environments. It also explains the causes of deadlocks and demonstrates how to simulate them using a sample Java program. It concludes by stressing the need to monitor and solve deadlocks for better performance.
The content outlines the process of optimizing Boomi performance, focusing on setting up a testing environment using a Boomi Atom on MacBook Pro. It highlights the challenges of performance issues, particularly thread deadlocks in Java applications. The use of tools like yCrash for diagnostics and monitoring is emphasized for identifying and resolving bottlenecks.
Spring Boot is a popular framework for developing Java web applications that often encounter thread deadlocks, halting performance. This blog discusses deadlock causes, examples, and troubleshooting techniques using the yCrash tool. Solutions include timeout locks, utilizing concurrency utilities, and avoiding nested locks to mitigate deadlock issues effectively.
The Spring Boot Buggy API is an open-source tool for simulating various performance issues like memory leaks and CPU spikes in applications. By testing these scenarios, developers can assess system resilience and evaluate performance monitoring tools. It allows easy invocation of specific problems to analyze system behavior and improve software robustness.
SpringBoot is a widely used framework for building Java-based web applications and maintains a significant presence in the world of enterprise software development. It powers large-scale microservices and standalone applications. Most SpringBoot applications have embedded web servers and follow a distributed architecture consisting of three main types of application components: Backend: API services Backend: Event...

We express our gratitude to Entwinkler.de JavaMagazin for translating our article ‘Simulating and troubleshooting deadlocks in Kotlin’ into German. It is an honor to have it published in their December 2022 issue as ‘Simulation und Fehlerbehebung von Deadlocks in Kotlin’.
This content discusses deadlock in multi-threaded applications, particularly in Scala. It explains deadlock as a situation where processes cannot proceed due to blocking, illustrated with a train example. The article also provides a sample Scala program creating deadlock and suggestions for troubleshooting using tools like yCrash to analyze thread dumps and logs.
JAX London is an annual October conference for Java and Software Architecture enthusiasts, attracting software engineers and enterprise professionals. In 2022, architect Ram Lakshmanan presented on "Let's crash your applications," focusing on creating sample code that triggers issues like memory leaks and deadlocks to aid in understanding and resolving software problems.
Apache PDFBox is a Java library for handling PDF documents. A recent deadlock issue was identified, blocking two threads that were waiting for each other's resources. Troubleshooting involved capturing thread dumps and analyzing them, which led to filing a bug report with the Apache PDFBox team, who promptly addressed the issue.
