for brevity) as a symptom. But as with any disease,not all OOMs necessarily imply memory leaks: an OOM can occur due to the generation of a large number of local variables or other such events. On the other hand,not all memory leaks necessarily manifest themselves as OOMs, especially in ...
HotSwap support: the object-oriented architecture of the Java HotSpot VM enables advanced features such as on-the-fly class redefinition, or "HotSwap". This feature provides the ability to substitute modified code in a running application through the debugger APIs. HotSwap adds functionality to th...
Based on investigations of real programs, previous work [3, 8] proposed two typical refactoring methods. One is atomic refactoring that allows the programmer to use an operation on a variable with a compare-and-swap operation in- stead of using the synchronized construct. This replaces opera- ...

The example demonstrates using the bitwise/logical exclusive OR operator to exchange (also known as swap) values without the need for a temporary variable. That "bitwise exclusive OR exchange" is just one of three techniques for exchanging variable contents. To see all of those techniques, check...
