At around the 1:48 mark you say, "... we look for the most high-level class." What does that phrase mean? Is that the class with the largest instance count? You chose the "GeneralPath" class? Why is the "GeneralPath" class the most high-level class? How do you determine which class is the "most high-level class?" Is a class in java.awt always higher than a class in java.util? If yes, then why?

Hi Sir, how to accomplish the same with a HPROF file? it tells me that the Allocations view is not available when viewing HPROF snapshots, thank you.

Hi Sir, I followed the same steps and only got the same results under "Allocations" by using "Instrumentation" mode, not with "Full Sampling", that means Full Sampling is not useful to find where are the offending objects being allocated? thanks

Does taking snapshot from heap and transferring thread dump take a long time for you too? It's taking me forever to do that.

How did you solve the leak in the end though? Why doesn't leakmap automatically free unused objects?
