  • 0

I used jprofiler to detect memory leak for my client code.At starting the memory used by java.util.hashmap$entry was increasing drastically up to 1700KB. after that it decreased too. The Heap dump show java.lang.ref.finalizer was using maximum of memory. What doest it conclude? When i try to find finalize() in my source code it was not there. in HTML file finalize() was used like this. finalize, what does it mean? The cause is finalize() or the reference hashmap$entry is causing the leak?

    If you want to look for a memory leak, you should look at how much memory is used after a Full GC, twice if you have lots of finalisable references, otherwise you are likely to see lots of temporary objects which don’t matter.

    I suspect neither of the data types you are seeing are a problem esp if they go down in usage periodically. Look for consumption which only goes up.
