The last book on the JVM itself (e.g. stack-based byte code, class file format) I saw was from nearly 20 years ago. I cannot think about anything more modern. It's a niche which used to be popular in FinTech circles mostly. As such valuable info was scattered across random blogs and the JVM spec itself.

"Garbage Collection: Algorithms for Automatic Dynamic Memory Management" (https://www.amazon.com/Garbage-Collection-Algorithms-Automat...) seems to cover GC algorithms up to the CMS.

"The Art of Multiprocessor Programming" (https://www.amazon.com/Art-Multiprocessor-Programming-Mauric...) is for those bored by JCiP. But it's not about threads per se. I imagine nobody cares about the original green threads and I wouldn't expect quality literature on the subject until project Loom goes to prod.

Actually C++ got a tracing GC API in C++11.

As for the rest, RC is GC.

Check chapter 5 in one of the most widely academic accepted books about GC algorithms.

Swift has a garbage collector.

Check chapter 5.

There is a lot of data on this topic.
