Many developers are either unaware of or prefer not to use JVM flags when running their Java applications, especially those requiring complex numerical inputs, such as memory-related flags. Despite the abundance of these flags, tuning even just one or two can significantly enhance application performance, which is critical in performance-sensitive scenarios. In this talk, I am going to explain an approach for auto tuning JVM flags that I studied in my master’s thesis which was in collaboration with Oracle. In my master's thesis, I explored five different machine learning models trained on data ..read more

Java 21 was an explosive release, but 22 to 24 are no slouches either: from unnamed patterns to module imports, from the foreign-function and memory API to stream gatherers and the class-file API, from a simpler main to launching multi-source-file programs, from Markdown in JavaDoc to improved garbage collection. There are plenty of features in the language, API, and runtime to discuss - whether new, improved, or finalized. So let's go over them!

Scoped values enable a method to share immutable data both with its callees within a thread and with child threads in a convenient, safe, scalable way, particular in comparison to thread-local variables. They are a preview feature in Java 24.
