Hello Clebert, thank you for the great tool. I have a question -- the number of references is overwhelming, even with the display limit of 200, so it's hard to find this very bad reference which prevents classloader to be gc-ed. Most of the references to the classloader however comes from its own classes(i.e. loaded by this classloader and its children), and should not be the problem. Is it possible to somehow filter references from the own classes and find that bad references from the container? Or am I generally misunderstanding something?
