Fixing the Java Memory Model

Anonymous Reader writes "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, the author shows how the semantics of volatile and final will be strengthened in order to fix the JMM. Some of these changes have already been integrated in JDK 1.4; others are slated for inclusion in JDK 1.5."
