Once you've managed it that everything is freed, you comment out the code for the weak references. Or if weak references are showing up, set them to null and mark it with a comment. Once you've found a hard reference where none should be, set it to null. I mainly used the last method, because it's the fastest way. A quicker way is to write add code to a ntextDestroyed() method and use introspection to poke some values to null.If you can't find the sources, translating the class back into readable code might work too.The best way would be to acquire all sources, but it's a hurdle.You found a hard reference? Remove it somehow: Since there are hard references also paths via weak references will show up. But the this will only find the first path.

In VisualVM you will use the context menu Show Nearest GC Root.

search hard references to the dead EarClassLoader instance.

start the server with the no deployed ear.

You quickly find that there is always one instance of an EarClassLoader for each deployed ear. VisualVM is a gui based tool which also allows to take heap snapshots and explore these snapshots. Jmap -dump:format=b,file=data.leak VisualVM Jhat and jmap are command line tools where jhat record a heap snapshot into a fileĪnd jmap starts a web server so you can browse the heap snapshot. But where do you start? First you need some tools. The plural is correct, it's more than one issue to find and eliminate. Once the glassfish is fixed, it looks like this: Preview of the result Tracking down the memory leaks You can clearly see the increasing count of loaded classes and how deployments are slowly eat your perm gen space. Have a look to the loaded classes after server start (having the ear deployed) and five successive deployments: If you are developing applications with glassfish you know what I'm talking about. The matter here is the memory leak in glassfish on ear undeployment Note that bugs get fixed time by time and this page is not updated frequently. Well, decide for yourself, if that slogan is true.
