As seen in the screenshot here, 0 live objects, 9 allocated objects. What's the difference between a live and an allocated object ?

The live objects are those objects that haven't been reclaimed by the garbage collector; this may include objects that are unreachable, and will definitely include objects that are still in use by the application.
Sampler panel: A simple sampling profiler You can control the sampling frequency and how often VisualVM updates the visualization. You can either profile CPU or Memory. Key Takeaway: Don't run a profiler in production.
Under the Local node in the Applications window, right-click the application node and choose Open to open the application tab. Click the Profiler tab in the application tab. Click Memory or CPU in the Profiler tab. When you choose a profiling task, VisualVM displays the profiling data in the Profiler tab.
The number of allocated objects is not the number of objects not yet reclaimed by the garbage collector. Rather, it is the number of objects created since application start, or since a reset of the "Collected Results Buffer" in VisualVM (there is a button in the memory profiler view to reset the collected results buffer).
The live objects are those objects that haven't been reclaimed by the garbage collector; this may include objects that are unreachable, and will definitely include objects that are still in use by the application.
