The Java Virtual Machine (JVM) maintains a run-time data area (called a heap) for the allocation of all class instances and array objects. The heap storage for objects is automatically reclaimed by a storage management system known as the garbage collector. If an application requires more heap space than can be made available by the garbage collector, the JVM throws an OutOfMemoryError.

HeapRoots analyses "heap dumps," which are files (typically text files) containing information about the objects in the JVM garbage collected heap. Some IBM VMs (contained in the IBM Developer Kits for Windows, Java Edition) have the ability to produce heap dumps on demand; heap dumps can also be triggered by out-of-memory situations.

HeapRoots offers you a simple means for memory leaks debugging.
