Monitor Non-Heap Memory in the Java Virtual Machine
https://www.javacodegeeks.com/monitor-non-heap-memory-in-the-java-virtual-machine.html
We're taking a holiday next Monday so there won't be a session next week. Please join us Monday, April 28th as Richard Fichtner joins us to share his real-world experiences using Quarkus.
If you're in #Tokyo on Tuesday (22 April), join me on JJUG for a walk-through #Java's virtual threads, structured concurrency, and how to implement a reactive-streams like library, in the "spirit" of Java 21+.
Hope to see you there! :)

One reason for my rejection of #SpringBoot for #java programs was their insistence on taking over object construction, and treating all objects as mutable. Mutability causes severe problems when multithreading and multiprocessing, features readily available in Java for quite some time. Now, Spring is deprecating #autowired in favor of immutable constructors, removing much of my initial criticism. Time for a second look!
