This tutorial aims to enable you to identify and resolve Not all memory leaks can be found this way, some require monitoring the memory allocation to find the real cause. Here, you can see the Objects that refer to the problematic objects, and you can probably detect which of your classes holds too many objects.
With JProfiler, analysing a heap dump is even simpler. The simplest way to find memory leaks is to analyse a heap dump of your program. How to find memory leaks in the PCM / Eclipse applications Analyse heap dump 1 How to find memory leaks in the PCM / Eclipse applications.
