What we’re about
Are you interested in Java or other JVM related programming languages and are you located or often found in or around Rotterdam? Join our JUG.
The goal of the Rotterdam JUG is to harvest the Java community in our area. To connect developers, build connections and to coach and help each other, to grow and share knowledge!

- 📢 Braving the Change & Deserialization exploits in JavaWeena 723, unit c5, Rotterdam
The RotterdamJUG is back, and we've got something special in store for you!
This time, we've managed to secure not 1, but 2 Java Champions!
Spoiler: one of them isn't even from the Netherlands!
This time, the event will take place on the 12th of March, and our host is Transtrend.

18:30: Braving the Change: recalibrating to new realities (Tom Cools)
Joining us, all the way from Belgium 🇧🇪, Tom Cools! Tom will be talking about keeping up with changing environments, with a focus on the impact of AI.
‘Change is the only constant in our industry’… but they never told us it would go this fast. With the recent evolutions in AI, ‘change’ has shifted from a ‘constant’ to something better described as ’exponential,’ sparking excitement for some and existential dread for others.
In this dynamic and insightful session, we’ll delve into the essential skills required to thrive in this rapidly evolving landscape. We’ll explore and discuss existing tools and frameworks that empower you to maintain momentum without losing control.
After leaving this session, you’ll be better prepared for whatever change might come on your path. And with preparation comes bravery.
19:30: Deserialization exploits in Java: why should I care? (Brian Vermeer)
Hackers refer to deserialization in Java as “the gift that keeps on giving”. But what is actually the problem? In most cases, it is not even your own code that creates this security vulnerability. This problem is also not restricted to Java’s custom serialization framework. When deserializing JSON, XML, or YAML, similar issues can occur as well.
In this talk, I explain how deserialization vulnerabilities work natively in Java and how attack chains are created. Next, I will show that deserializing XML, JSON, and YAML can also get you into trouble. And of course, we had the recent Log4j problems with deserialization. Many different problems can occur when deserializing data and in this session, I will use several demos to illustrate various security issues. How do you avoid these issues? I will give you some pointers on how to mitigate these problems in your own applications, this also includes new features in Java. At the end of this session, you will have an understanding of the problem space and be able to take action in your code to prevent it.
20:30: Networking/Drinks 🥤
21:30: Time to go home 🚉
