Your production Java application stops working. An angry customer is waiting for a fix. Your boss is on the line asking what's going on...

We have all been there. In such situations solving problems quickly makes you trusted and shows your maturity as a developer. That's what being a senior developer looks like.

This presentation will guide you through a little-known infallible process used by the top Java experts that can get you out of very hard situations! Troubleshoot any problem in your Java applications by using free and open-source tools available in the JDK -- jps, jinfo, jmap, jstack, jcmd, jhsdb, and jdb.

Be the go-to person in your team to solve hard problems! Understand the common problems professional Java developers face and how to diagnose and solve them quickly.

Are you sure your concurrency code will not fail?

Writing concurrent programs is hard. Testing the concurrent program is harder. Debugging the concurrent program is a nightmare.

The incorrect concurrent program can run for years, tricking us to believe it is stable code. And then fail spectacularly when we least expect.

Why run this risk when OpenJDK provides an amazing tool to test the correctness of your concurrent programs?

Meet JCStress. A concurrency stress test tool used by JVM developers to test the correctness of the JVM itself!

In this session, you will understand how to use JCStress and how to test your concurrent programs. You will write tests and learn how to deal with different scenarios.

Start using JCSTress on your projects today. Eliminate the risk of catastrophic concurrency failures in your Java applications. Test now so you don't have to debug it later.
