Edit Question
Title
Body
Suppose our code has 2 threads (A and B) have a reference to the same instance of this class somewhere: public class MyValueHolder { private int value = 1; // ... getter and setter } When Thread A does myValueHolder.setValue(7) , there is no guarantee that Thread B will ever read that value: myValueHolder.getValue() could - in theory - keep returning 1 forever. In practice however, the hardware will clear the second level cache sooner or later, so Thread B will read 7 sooner or later (usually sooner). Is there any way to make the JVM emulate that worst case scenario for which it keeps returning 1 forever for Thread B? That would be very useful to test our multi-threaded code with our existing tests under those circumstances.
