Read-write locks allow multiple threads to acquire a read lock provided no other thread currently has a write lock on the same object. A thread can acquire a write lock if no other thread owns either a read lock or a write lock.
In this article, Brian Goetz looks at some of the commonly proposed fixes and shows how each of them fails to render the DCL idiom thread-safe under the Java Memory Model.
Discusses architectural solutions to threading problems. Takes a look at threads from the perspective of an object-oriented designer, and at how to implement threads in an object-oriented environment, focusing on the implementation of asynchronous met...
Many authors advocate the double-checked locking idiom to access a Singleton object in an intuitively thread-safe way. Unfortunately, for counterintuitive reasons, double-checked locking doesn't work in Java.
