How to find out what objects exist

General

Hi everybody!
I need help again. Well, I’m not a very expirienced developer.

Could you please tell me, is there any tool, that can show me what objects are created? Looks like I have a memory leak in my vaadin6 project, and I have no idea how to find the core of this problem.

You can use either VisualVM (free, included with the JDK) or JProfiler (commercial and more powerful). Both have a feature to record object allocations.
