Finding and Solving Java Deadlocks Workshop with Dr Heinz Kabutz

One of the hazards of multithreaded code is that if we are not careful, we might cause a deadlock in our program. The simplest of these is the “deadly embrace,” in which locks are acquired by multiple threads in different orders. The simple deadlocks can be detected automatically with the deadlock detection tool in the ThreadMXBean. However, there are also other types of deadlocks that cannot be detected automatically and that require analysis of the stack traces of all the threads, just as in the good old days. This hands-on-lab explains what causes deadlocks and how to find them. You will then be given a body of code to test for deadlocks, using the techniques learned.

Dr Heinz Kabutz

Heinz Kabutz has been writing Java deadlocks since 1997. His first deadlock occurred when he tried to bullet-proof his code by having two locks around the database code. In one place he forgot one lock, leading to a deadly embrace. At the time, deadlocks could only be found manually and with a fair amount of effort. Heinz started his Java Specialists' Newsletter in 2000 with an article on deadlock detection. He has since written over 200 articles on a variety of topics to do with advanced Java.

Heinz was chosen as a Java Champion in 2005 for his work in promoting Java through his newsletter, now read by 50000 Java programmers in 126 countries.

Pre-requisites for the lab:

- You must bring your laptop with Java 6 or 7 installed, your favorite IDE

- Knowledge of Java 5/6 concurrency

    Awesome session by Dr. Kabutz. Would be great if we could have more lab-format sessions on advanced topics. Dario - thanks for Pizzas and putting this session together.

    Great lab, great presentation - thanks Dr. Kabutz...the only thing missing is Will Ferrell grabbing the mic at the end and yelling "and THAT's how you do a LAB!"

    In case anyone needs still...enter off of Spruce street, center of building when looking at the map (enter at larger Pace Univ entrance). Tell them "south lecture hall", 2nd floor. Walk straight down hall to lockers, then left to Courtyard, thru Courtyard, enter building again, take elevators on the right to 2nd floor, follow signs to south lecture hall. Yep it's slightly involved. :)
