Java Memory Model Pragmatics

Abstract: Java Memory Model (JMM) specification tries to be very concise yet complete. Because JMM tries to embrace a very large set of phenomenon, its formalism is very heavy, which unfortunately resulted in losing the “humanity” of the spec.

In this talk, we will follow the logic of the model; review what pragmatic results the model was trying to achieve; look closely at the real world limitations the model had to endure; see how JMM tries to balance between developers’ needs and runtime/hardware maintainers requests.
