Ask HN: Best Books on the JVM?
57 points by abadger9 13 days ago | hide | past | favorite | 6 comments
I've worked on JVM languages for a decade, and know it from a practical standpoint, but would like to dive into the internals of garbage collection, memory pools (eden space, survivor space), and threads (virtual threads, green threads, etc)

I strongly recommend following and listening to videos by Cliff Click who wrote HotSpot and worked on Azul and other VMs.

Cliff also has Coffee Compiler Club sessions on Fridays.

It's not a book but Shipilev's Quarks are an excellent source for some of the more obscure corners:


BTW green threads haven't been used for decades ;)

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.

I would recommend the following:

  The Garbage Collection Handbook: The Art of Automatic Memory Management [1] 
[1] https://www.amazon.com/dp/0367659247

Java Performance: The Definitive Guide, by Scott Oaks is great. https://www.oreilly.com/library/view/java-performance-the/97...
