**About this event:**

The LJC back with the second in our new series of events, aimed at giving all Community members an opportunity to present at an LJC meet-up.

If you have an interesting topic to share, this event is for you. You don’t have to be an experienced speaker - we want to hear your story and offer you a friendly, informal platform to practise and improve your presentations.

For attendees we want this to be a meeting place, where you can talk and network with other technologists in London.

If you’d like to speak at a future event, please submit your talk and bio details here: [https://sessionize.com/ljc/](https://sessionize.com/ljc/ "https://sessionize.com/ljc/")

Talk: **Could Virtual Threads cast away the usage of Kotlin Coroutines? What experience can tell us**

Kotlin coroutines have been around since 2017 and have contributed to defending the usage of Kotlin in everything from Android development to multi-platform, to developing highly available and resilient services making optimised use of resources, and allowing threads to be available as soon as possible. The use of coroutines also implicated the usage of context and scopes, which for many became complicated abstract concepts. And then Java 21 was released in 2023 and while researching and applying this at work I realised that in some places, it makes sense to remove the usage of coroutines and replace them with virtual threads. On the other hand, in other places, the usage of Kotlin coroutines seems to remain justified.

In this session I will talk about funny examples and real-life problems that I found on the field, why they occurred, and how I solved them. We may find a common ground between Java Virtual Threads and Kotlin Coroutines, or maybe not.

After this session, you will come out with a different understanding of what Kotlin Coroutines and Java Virtual Threads have to offer. You'll be able to make better-informed decisions on how both work, so that you can independently suggest solutions in your team, at work, or on your own time.

1\. Quick understanding of JVM Architecture
2\. Garbaze collection
3\. Profiling and monitoring tools
4\. Dealing with JVM crashes and OutOfMemory Errors
5\. JVM Tuning technique and continuous improvement
