Deadlock-Free Synchronization in Java

The only surefire way to prevent them is properly designing your code, which is the subject of this article. We will take a look at the origin of deadlocks, consider a method for discovering potential deadlocks in existing code, and present practical approaches to designing a deadlock-free synchronization.

This means that we associate each lock with a unique constant index, and always acquire locks in the order defined by their indices.

We also studied why and how such designs work, what the limits of their applicability are, and how to efficiently find and fix the potential deadlocks in the existing code.
