problems with the Java memory model on IBM's developerWorks.
"JSR 133, which has been active for nearly three years, has recently issued its public recommendation on what to do about the Java Memory Model (JMM). Several serious flaws were found in the original JMM, resulting in some surprisingly difficult semantics for concepts that were supposed to be simple, like volatile, final, and synchronized. In this installment of Java theory and practice, Brian Goetz shows how the semantics of volatile and final will be strengthened in order to fix the JMM.
