JAVA threads

For example, in the following (broken) code fragment, assume that this.done is a non-vol- atile boolean field:

while (!this.done) Thread.sleep(1000);

The compiler is free to read the field this.done just once, and reuse the cached value in each execution of the loop. This would mean that the loop would never terminate, even if another thread changed the value of this.done.
