You might want to try the memory leak detector that comes with JRockit Mission Control along with the Eclipse MAT . This is a powerful combination. Both tools are free to use for development.

With JRockit Mission Control, you can check a bunch online and see the exact numbers of objects of a certain type that are live, without having to take temporary snapshots. You can immediately see if you have an editor, view, or listener left after the heap after closing View / Editor. This is usually a framework listener, which is stored in your view / editor. Remember that you have to go to Windows-> Preferences-> Memory Leak Detector-> Trend and set the Lowest Heap Usage to report 0.0 for all instances of the object.

Using MAT, you can use the shortest path to the root of the stream to find the chain that holds the leak object. See below
