The Java Memory Model

Throughout this book, we've mostly avoided the low-level details of the Java Memory Model (JMM) and instead focused on higher-level design issues such as safe publication, specification of, and adherence to synchronization policies. These derive their safety from the JMM, and you may find it easier to use these mechanisms effectively when you understand why they work. This chapter pulls back the curtain to reveal the low-level requirements and guarantees of the Java Memory Model and the reasoning behind some of the higher-level design rules offered in this book.
