HeapWalker is a tool useful for evaluating Java heap contents and searching for memory leaks. It allows you to view: List of classes which are present on the heap. For each class you can see number of it's instances and total size of all instances. List of instances of each class. You can see individual instances and their size (size of instances of the same class varies only for arrays). Fields of each instance or class. You can browse (static) fields to identify individual instances by field values and determine dependencies among them. References to each instance. You can browse instances or classes holding reference to a particular instance to find unnecessary references and discover memory leaks.
