Caroline’s Reviews > Java Concurrency in Practice > Status Update

Chapter 16 - One of these days, I should read the actual Java memory model. But in the meantime, having a nice summary was helpful.

Chapter 15 - The lock-free queue algorithm presented here was fascinating.

Chapter 13 - I didn't really understand explicit Lock objects in Java before. Good to know, I guess. Although honestly I really love Java's synchronized keyword.

Chapter 12 - Lots of great advice here!

A lot of this was stuff I knew or common sense. Still, I have a feeling I'll be coming back to this chapter if I'm ever seriously trying to improve the performance of a concurrent program.

Chapter 10 - Interesting contrast of Java with database systems. I usually take it for granted that deadlock will be unrecoverable, but it's a good point that there are real world systems that very often recover! The pattern of "open calls" also sounds very useful and is not something I had considered before.

Chapter 9 - "If you've tried to write even a simple GUI application using Swing..." No, I haven't. Maybe I should have skipped this chapter.

Chapter 8 - Very interesting, although not as relevant if you're used to working with higher level third party execution frameworks instead of managing your own thread pools.

Chapter 7 - I've spent surprisingly little time in my career making sure the programs I write are responsive to cancellation. Still, it's interesting to know the intention behind InterruptedException. I have to wonder about the design choice, though, since it forces every program to handle InterruptedException even though many might not care about supporting cancellation. What a pain.

Chapter 6 - This is a very useful chapter. ExecutorService is a must have for concurrent code, and the chapter clearly explains why.
